Simple pendulum of length l has a maximum angular displacement . The maximum kinetic energy of the bob is
Options
- Am g l(1- )
- B0.5 mgl
- Cmgl
- D2 mgl
Correct answer
A. m g l(1- )
Step-by-step solution
In the equilibrium position energy is in the form of kinetic energy. Height of bob at maximum angular displacement is aligned h & =l-l & =l(1- ) Also PE & = KE m g h & =m g l(1- ) aligned
