Two spherical point charges each carrying a charge of 40 μC are attached to the two ends of a spring of length 20 cm. If its spring constant is 120 Nm-1 , what is the length of the spring when the charges are in equilibrium?

Explanation:

From the question we are told that:

Charge

Length

Spring constant

Generally the equation for Force between Charges is mathematically given by

Therefore
