Five particles each of mass 'm' are kept at five verties of a regular pentagon . A sixth particles of mass 'M' is kept at center of the pentagon 'O'.Distance between'M' and is 'm' is 'a'. Find   (a) net force on 'M'  (b) magnitude of net force on 'M' if any one particle is removed from one of the verties.
