(a) If both assertion and reason are true and reason is the correct explanation of assertion.
(b) If both assertion and reason are true but reason is not the correct explanation of assertion.
(c ) If assertion is true but reason is false.
(d) If assertion and reason are false.
Q. Assertion: Strain is a unitless quantity.
Reason: Strain is equivalent to force.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: Steel is more elastic than rubber. Reason: Under a given deforming force steel is deformed less than rubber.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: Stress is the internal force per unit area of a body. Reason: Rubber is more elastic than steel:

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: For small deformation, the stress and strain are proportional to each other. Reason: A class of solids called elastomers does not obey Hooke's law. Reason: A class of solids called elastomers does not obey Hooke's law.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: The stress-strain behaviour varies from material to material. Reason: A rubber can be pulled to several times its original length and still returns to its original shape.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: Lead is more elastic than rubber. Reason: if the same load is attached to lead and rubber wires of the same cross-sectional area, the strain of lead is very much less than that of rubber.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: When height of a tube is less than liquid rise in the capillary tube, the liquid does not overflow. Reason: Product of radius of meniscus and height of liquid in capullary tube always remains constant.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: It is easiar to spray water in which some soap is dissolved. Reason: Soap is easier to spread.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: The bridges are declared unsafe after long use. Reason: Elastic strength of bridges losed with time.

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: At critical temperature, surface tension of a liquid becomes zero. ltbr. Reason: At this temperature intermolecular forces for liquids and gases become equal. Liquid can expand without any restriction.

In the following question, a statement of assertion is followed byb a statement of reason, mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If both assertion and reason are false. Q. Assertion: Steel and brass are more elastic than copper and aluminium. Reason: That's why they are preferred in heavy-duty machines and in structural designs.
