Particle in a shell
A particle is given an initial speed inside a smooth spherical shell of radius so that it is just able to complete the circle. Find the acceleration of the particle, when its

For the block to complete the round. there's required a centrepretal force equal to it's weight. So we get minimum velocity required to comm[lete round v=(5gr)^1\2 . then by work energy theorem we get v at position where it's velocity is vertical. And finally a vector addition of gravity and acceleration of the block
