A particle slides down a smooth inclined plane of elevation , fixed in an elevator going up with an acceleration a0 (figure). The base of the incline has a length L. Find the time taken by the particle to reach to the bottom -

Options

A. `[(2L)/(g sin theta cos theta )]^(1//2)`
B. `[(2L)/((g-a_(0))sin thetacos theta )]^(1//2)`
C. `[(2L)/((g+a_(0))cos theta )]^(1//2)`
D. `[(2L)/((g+a_(0))sinthetacos theta )]^(1//2)`

Answer

D
