A radioactive source in the form of a metal sphere of daimeter 10^−3 m emits β-particles at a constant rate of 6.25×1010 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 β-particles escape the socurce?
