Assertion: For motion in two or three diemensions, velocity and acceleration vecotrs must have any angle between `0^(@) and 90^(@)` between them.
Reason: For such motion velocity and acceleration of an object is always in the opposite direction.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

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

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
d
In one diemension, the velocity and the acceleration of an object are always along the same straight line either in the same direction or in the opposite direction. However, for motion in two or three dimension velocity and acceleration vectors may have any angle between `0^(@) and 180^(@)` between them.
