Question

Suppose the magnitude of the proton charge differs from the magnitude of the electron charge by a mere 1 part in 10^9, i.e., qp = −qe (1 + 10^−9).
--------------------------
(a) What would be the force between two 2.0-mm-diameter copper spheres 1.8 cm apart? Assume that each copper atom has an equal number of electrons and protons.

(b) Would this amount of force be detectable? What can you conclude from the fact that no such forces are observed?

Answer 1

What is the charge on the spheres? If the objects are neutral, there wont be a force.

Answer 2

thank you I found the answer

Answer 3

okay cool
