A radioactive source, in the form of a metallic sphere of radius `10^(-2)m` emits `beta-`particles at the rate of `5xx10^(10)` particles per second. The source is electrically insulated. How long will it take for its potential to be raised by `2V`, assuming that `40%` of the emitted `beta-`particles escape the source.

A radioavtive source in the form of a metal sphere of daimeter 10^(-3) m emits beta -particles at a constant rate of 6.25 xx 10^(10) particles per second. If the source is electrically insulated, how long will it take for its potential to rise by 1.0 V , assuming that 80% of the emitted beta -particles escape the socurce?
