Question

A conducting cylinder of radius 3.25 cm and length 5.6 cm has a total charge of 5.5 x 10^-9 C distributed uniformly on its surface area. Find for the potential at its surface.

Answer 1

Answer

conducting cylinder of radius

R=3.25 cm and

length L=5.6 cm

total charge of q=5.5 x 10^-9 C

Potential is given by

$V=\frac{\lambda}{2\pi \epsilon_0}\ln(\frac{r}{R})$

For surface r=R

So logrithm term become zero. So potential at surface will be zero.
