A body executes simple harmonic motion. The potential energy (P.E), the kinetic energy (K.E) and energy (T.E) are measured as a function of displacement `x`. Which of the following staements is true?

Options

A. (a) K.E. is maximum when `x=0`.
B. (b) T.E is zero when `x=0`
C. (c ) K.E is maximum when x is maximum
D. (d) P.E is maximum when `x=0`

Answer

A

Explanation

(a) `K.E.=1/21/2 momega^(2)(a^(2)-x^(2)`.
Where `x=0`, K.E is maximum and is equal to `1/2momega^(2)a^(2)`.
