The correct option(s) is/are
[where \( x= \) compression]
(1) Gravitational potential energy is decreased and its magnitude of \( m g x \sin \theta \)
(2) Elastic potential energy stored in spring \( =1 / 2 k x^{2} \)
(3) Total potential energy of the system \( =-m g x \sin \theta+1 / 2 k x^{2} \)
(4) None of these
