A radioactive source in the form of a metal sphere of diameter 3.2×10^ −3 m emits β-particle at a constant rate of 6.25×10^ 10 particle/sec. The source is electrically insulated and all the β-particle are emitted from the surface. The potential of the sphere will rise to 1 V in time

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?
