Electric Charges and Fields – Solutions
1) What is the force between two small charged spheres having charges of 2 x 10-7 C and 3 x 10-7 C placed 30 cm apart in air?
Solution:
Electrostatic force between the spheres is given by the relation,
F = q1 x q 2/4πεor2
Where q1 = charge on the first sphere
q 2 = charge on the second sphere
r = distance between the sphere
ε0 = Permittivity of free space
