Assertion:Mass is a measure of inertia of the body in linear motion.
Reason: Greater the mass, greater is the force required to change its state of rest or of uniform motion.

A

If both assertion and reason are ture and reason is the correct explanation of assertion.

B

If both assertion and reason are ture but reason is not the correct explanation of assertion.

C

If assertion is ture but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Acceleration to Newton's second law of motion `a=(F)/(m)` i.e., magnitude of the acceleration produced by a given force is inversely proportional to the body, lesser will be the acceleration produced i.e., mass of the body is a measure of the opposition offered by the body to change a state, when the force is applied i.e., mass of a body is the measure of its inertia.

    How a force can change the state of motion?

    The greater the mass of a body the greater is its heat capacity is this true of false?

    Name the property of bodies due to which they resist change in their state of rest or state of uniform motion along a straight line.

    The greater the mass of a body, the greater is its specific heat capacity. True of false?

    Assertion : An external force is required to keep a body in motion. Reason : If the net external force is zero, a body at rest continues to remain at rest and a body in motion continues to move with a uniform velocity.
