A drop of water of mass m falls away from the bottom of charged conducting sphere of radius R, carrying with it a charge `q_(1)` and leaving the sphere a uniformly distributed charge `q_(2)`. The kinetic energy of the drop after it has fallen height h is -

A drop of water of mass 18xx10^-3 g falls away from the bottom of a charged conducting sphere of radius 20 cm, carrying with it a charge of 10^(-9)C and leaving on the sphere a uniformly distributed charge of 2.5xx10^(-6)C . What is the speed of the drop after it has fallen 30 cm? (4piepsi_(0))^(-1)=9xx10^(9)JmC^(-2)
