A small particle is placed at the topmost point of a paraboloidal cavity made inside a wedge , which is placed on a smooth horizontal surface as shown . There is no friction anywhere . It has been observed that just after release of particle from the top as shown acceleration of wedge is an . What is the acceleration of centre of mass of this system just after release ? The system is placed in unknown uniform gravity . Use m m R M = k H MA small particle is placed at the topmost point of a paraboloidal cavity made inside a wedge , which is placed on a smooth horizontal surface as shown .
