7. When a particle executing a linear S.H.M. moves from its extreme position to the mean position,
its
(A) K.E. decreases and potential energy increases
(B) K.E. increases and potential energy decreases
(C) Potential energy becomes zero but kinetic energy remains constant
(D) Potential energy increases but the K.E. becomes zero​

Answer 1

Answer:

b

Explanation:

potential energy at point O is Mgh

at point P is zero.

at point P potential energy is zero that implies kinetic energy is maximum
