(3) ymax 11 mA bob hangs from a rigid support by an inextensible string of length e. If it is displaced through a distance e (from themax6.n) keeping the string straight & then released. The speed of the bob at the lowest position is:(2) 3g(3) /2g(4) V5gge

Answer»

When block is displaced by the displacement l then

Change in potential energy = gain in kinetic energy

Mgl = 1 / 2 mv^2

V= square root of 2gl

Hence, the answer is square root of 2gl
