The length of a simple pendulum of 0.4 m. The bob of the pendulum is drawn aside till the string is horizontal, it is then released from this horizontal position, What will be its velocity when it reached the lowest point in its swing ? `(g = 9.8 m//s^(2))`
[Hint : Loss in potential energy = gain in kinetic energy]
