Assertion: The scalar product of two vectors can be zero
Reason: If two vectors are perpendicular to each other their scalar product will be zero.

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 aseertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
If `theta` be the angle between two vectors `vec(A)` and `vec(B)`, then their scalar product, `vec(A).vec(B)= AB cos theta`
If `theta= 90^(@)` then `vec(A).vec(B)=0`
i.e., if `vec(A)` and `vec(B)` are perpendicular to each other then their scalar product will be Zero.
