What is the force between two small charged spheres having charges of 2 × 10–7C and 3 × 10–7C placed 30 cm apart in air?
Given, the charge on the particles are 2 × 10 − 7 C and 3 × 10 − 7 C . The distance between the charges is 30 cm .
The electrostatic force between the charges is given by the equation,
F = 1 4 π ε 0 × q 1 q 2 r 2
Substituting the values in the above equation, we get:
F = 9 × 10 9 N ⋅ m 2 / C − 2 × 2 × 10 − 7 C × 3 × 10 − 7 C ( 30 × 10 − 2 m ) 2 = 6 × 10 − 3 N
The electrostatic force between the charges is 6 × 10 − 3 N and it is repulsive in nature.
Given, the charge on the particles are
The electrostatic force between the charges is given by the equation,
Substituting the values in the above equation, we get:
The electrostatic force between the charges is
