An excessive charge of 500 trillion electrons is dumped at t=0 within an aluminum sphere of radius 10 cm. What is the amount of excess charge? Assuming the dielectric constant of aluminum is unity, what is the relaxation time? How long does it take for the charge to decrease to 80% of its initial value? answer obtained by my teacher : -80 uC and 56*10^-21 s.
