Question
An object of mass 0.5 kg is executing simple harmonic motion. It amplitude is 5 cm and time period (T) is 0.2 s. What will be the potential energy of the object at an instant $\mathrm{t}=\frac{T}{4} s$ tarting from mean position. Assume that the initial phase of the oscillation is zero.
Select the correct option:
A
0.62 J
B
$6.2 \times 10^{-3} \mathrm{~J}$
C
$1.2 \times 10^3 \mathrm{~J}$
D
$6.2 \times 10^3 \mathrm{~J}$
