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?
question : -
Answer :-
Repulsive force of magnitude
Charge of the first sphere
Charge of the second sphere
Distance between the spheres, r = 30 cm = 0.3m
Electrostatic force between the spheres is given by the relation,
Where, E0 = Permittivity of free space
Hence, force between the two small charged spheres is
The charges are of same nature. Hence, force between them will be repulsive.
