Question

What are (a) the charge (in C) and (b) the charge density on the surface of a conducting sphere of radius 0.19 m whose potential is 260 V (with V = 0 at infinity)?

Answer 1

For the charge, I calculated \(q=5.49499\times10^{-9}~C\)
Sig figs not accounted for of course.

Answer 2

You already calculated the charge.

By symmetry, surface charge density = Charge / Surface Area
