Question

Two charges, shown below, are attracted to each other. But one is attached to a spring. The other is fixed. When the fixed charge is removed, the charge on the spring moves to its 'rest position.' What is the spring constant of the spring?

charges, shown below, are attracted to each other. But one is attached ring. The other is fixed. When the fixed charge is removed, the charge spring moves to its 'rest position'. What is the spring constant of the Coulombs Law vs the Law of Gravity identical 2 micro coulomb charges also have identical mass. They are at What mass must they have? (Consider only the gravitational force and caused by the charge. )

Explanation / Answer

k x = K q1 q2/r^2

==> k = K q1 q2/(x r^2)

==> k = 8.99e9*(4e-6)*(6e-6)/(0.2*(3e-3*3e-3))

==> k = 1.20 x 10^5 N/C
