A small block of mass ‘m’ is kept on a smooth inclined plane of angle 30^o placed in an elevator going upward with acceleration ‘a’. Electric field E exists between the vertical sides of the wall of elevator. The charge on the block is +q. The time taken by the block to come to the lowest point of the inclined plane is (Take the surface to be smooth.)
