A pendulum is suspended by a string of length $250cm$ . The mass of the bob of the pendulum is $200g$ . The bob is pulled aside until the string is at $60 °$ with vertical as shown in the figure. After releasing the bob, the maximum velocity attained by the bob will be _____ $m{s}^{- 1}$ . (if $g = 10m{s}^{- 2}$ )

A pendulum is suspended by a string of length 250cm . The mass of the bob of the pendulum is 200g . The bob is pulled

Velocity will be maximum at the bottom point when potential energy of the pendulum will be zero(considering bottom point as reference for potential energy).

$\dfrac{1}{2}m{v}^{2} = mg\left(l - lcos60 °\right)v = \sqrt{gl} = \sqrt{10 \times 2 . 5} = 5m{s}^{- 1}$
