Assertion: A null Veactor is a vector whose magnitude is zero and directon is arbitrary.
Reason: A null vector does not exist

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
A null vector has direction which is indeterminate (depends on direction of initial vectors) even its magnitude is zero. If two vectors equal in magnitude are in opposite direction, then their sum will be a null vector.

What is a null vector ?

Assertion: A physical quantity cannot be called as a vector if its magnitude is zero. Reason: A vector has both, magnitude and direction.

Assertion : A vector can have zero magnitude if one of its rectangular components is not zero. Reason : Scalar product of two vectors cannot be a negative quantity.

Assertion :- Unit vector is used to describe a direction in space. Reason :- Unit vector has a unit through its magnitude is one.

Assertion (A): A physical quantity which can be described with both magnitude and direction is called as a vector quantity. Reason (R): All vector quantities are derived quantities.

While delivering a lecture on vectors Phusics teacher told the students about zero vector or mnll vector, i.e. a vector which has zero magnitude and arbitray direction. It is represented by vec 0 (arrow ovet the numnet zero . The students wer baffled. Read the above passage and answer the following questins : (i) What was the becessity of the concept zero vector ? ltbRgt Give any one illustravion of zero vector. (ii) What is the phusical significane of zero vector ?

Assertion: The minimum number of vectors of unequal magnitude required to produce zero resultant is three. Reason: Three vectors of unequal magnitude which can be represented by the three sides of a triangle taken in order, produce zero resultant.

Minimum No of Non-coplanar vector whose resultant is zero is
