A particle slides down a smooth inclined plane of elevation `theta` fixed in a elevator going up with an acceleration `a_(0)`. The base of the inline has a length L.

Options

A. The acceleration of the particle with respect to the incline plane is `( g+ a_(0)) cos theta `
B. The time taken by the particle to reach the bottom `((2L)/((g+a_(0))sin theta))^(1//2)`
C. The acceleration of particle with respect too the incline plane `( g + a_(0)) sin theta `
D. The time taken by the particle to reach the bottom `((2L)/((g+a_(0))sin theta cos theta))^(1//2)`

Answer

C, D
