A simple pendulum of length $L$ has mass $M$ and it oscillates freely with amplitude $A$. At the extreme position, its potential energy is ($g$ = acceleration due to gravity)

• Correct answer
  A

  $\frac{Mg{A}^2}{2L}$
• B

  $\frac{MgA}{2L}$
• C

  $\frac{Mg{A}^2}{L}$
• D

  $\frac{2Mg{A}^2}{L}$

Hence, the correct answer is option: 'A'.
