A sphere of radius ` 0.1m` and mass `8 pi kg` is attached to the lower end of a steel wire of length `5.0 m` and diameter `10^(-3)`. The wire is suspended from `5.22 m` high ceiling of a room . When the sphere is made to swing as a simple pendulum, it just grazes the floor at its lowest point. Calculate the velocity of the sphere at the lowest position . Young's modulus of steel is `(1.994xx10^(11) N//m^(2))`.

A sphere of radius 0.1 m and mass 8pi kg is attached to the lower end of a steel wire of length 5.0 m and diameter 10^(-3) m. The wire is suspended from 5.22 m high ceiling of a room. When the sphere is made to swing as a simple pendulum, it just grazes the floor at its lowest point. Calculate the velocity of the sphere at the lowest position. Y for steel =1.994xx10^(11)N//m^(2) .

A sphere of mass 2 kg and diameter 4.5 cm is attached to the lower and of a steel wire of 2 m length and are of cross- section 0.24 xx 10^(-6)m^2 . The wire is suspended from 205 cm high ceilling of a room. When the system is made to oscillate as a simple pendulum, the sphere just grazes the floor at its lowest psition. The velocity of the sphere at the lowest position is (young's modulus of steel =2xx 10^(11) Nm^(-2) and acceleraiton due to gravity =10 ms^(-2))
