The displacement (x) of a particle is given by `x= a sin (bt+c)` where a, b and c are constants of motion.
Select the incorrect statement from the following .

Options

A. The energy of the particle in simple harmonic motion remains constant
B. The velocity of the particle is zero at `x=+-a`.
C. The acceleration of the particle is zero at `x=+-a`.
D. The motion represented by the given equation repeats itself a time interval `(2pi)/(b)`

Answer

C

Explanation

Acceleration of the partile is maximum at `a=+-a`.
