A nonconducting sphere has a radius R=9.5 cm and uniformly distributed charge q=5.5e-12 C. Take the electric potential at the sphere's center to be zero. What is V at radial distance r=5.8 cm?
Homework Answers
At any given distance r from center, electric potential would be,
V = (1/4
o)xQ(3R2-r2)/2R3
= 9x109x5.5x10-12x(3x0.0952 - 0.0582)/2x0.0953
=4.95x10-2x0.0239/0.001714
=0.07 v
so, electric potential at r=5.8cm is 0.07 Volts.
