A simple pendulum of length 'L' has mass 'm' and it oscillates freely with amplitude 'A' At extreme position, its potential energy is (g =acceleration due to gravity)
Options
- Am g A² 2 L
- Bm g A² L
- CmgA L
- Dm g A 2 L
Correct answer
A. m g A² 2 L
Step-by-step solution
PE = m ² x ² 2 = g L , at extreame point x = A So PE = MgA ² 2 ~L
