A block slides down from top of a smooth inclined plane of elevation `theta` fixed in an elevator going up with an acceleration `a_0` The base of incline has length L. Find the time taken by the block to reach the bottom.

Options

A. `[(4L)/((g+a_0)sin2 theta)]^(1/2)`
B. `[(4L)/((g+a_0)sin theta)]^(1/2)`
C. `[(4L)/((g-a_0)sin theta)]^(1/2)`
D. `[(4L)/((g-a_0)sin 2theta)]^(1/2)`

Answer

A
