Describe the direction of the electric force between two opposite charges, betwe
charges and when a charge is in an electric field.

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.

You notice the birds sitting on the electrical wires which of the following explain why the birds don't get shocked
