# A particle executing simple harmonic motion comes to rest at the extreme positions.Is the resultant force on the particle zero at these positions according to Newton's first law?

A.

No.

Because x = A, at extreme.

and Force is given as  $F=-kx$

So $a= max\ at\ extreme\ position, i.e., at\ x=\pm A, \ a=\pm\omega^2A$
