A sphere of radius r is kept on a concave mirror of radius of curation `R`. The arrangement is kept on a horizontal surface (the surface of concave mirror is friction less and sliding not rolling). If the sphere is displaced from its equilibrium position and left, then it executes `S.h.M.` The period of oscillation will beA. `2pi sqrt([(R-r)1.4//g])`B. `2pi sqrt([(R-r)//g])`C. `2pi sqrt([(Rr//g)])`D. `2pi sqrt([(R//gr)])`

Answer» Correct Answer - A
`T = 2pi (sqrt(((R-r)(1+beta))/(g)))`
