A

`vecL_(O)` and `vecL_(P)` do not vary with time

B

`vecL_(O)` varies with time while `vecL_(P)` remains constant.

C

`vecL_(O)` remains constant while `vecL_(P)` varies with time.

D

`vecL_(O)` and `vecL_(P)` both vary with time

Text Solution

Verified by Experts

The correct Answer is:
C
Direction of `vecL_(P)` will keep on changing
