The horizontal acceleration that should be given to a smooth inclined plane of angle sin^(-1)((1)/(l)) to keep an object stationary on the plane, relative to the inclined plane is

Answer»

`(G)/(SQRT(l^(2)-1))`
`gsqrt(l^(2)-1)`
`(sqrt(l^(2)-1))/(g)`
`(g)/(sqrt(l^(2)+1))`

SOLUTION :Resolve mg and pseudo FORCE into components
At equilibrium `mg sin theta=ma cos theta`
