Homework Statement
A sphere with radius 65 cm has its center at
the origin. Equal charges of 4 μC are placed at
60◦ intervals along the equator of the sphere.
What is the electric potential at the origin?
Homework Equations
V=KQ/R
The Attempt at a Solution
I just plug the numbers in this equation but no good.
I think it might have to do with the degree sign or its on the origin.
Note: I did not do sine or cosine for the degree because my notes did not show any sine or cosine for electric potential.
