Forces between multiple charges – Superposition principle
o
o
Is inversely proportional to square of the distance between these charges and
Is directly proportional to product of magnitude of the two charges
o Acts along the line joining the two point charges.
Here ε 0 = 8.854 x 10-12 C 2 N-1 m-2 is called permittivity of free space.
