1. Two protons at rest and separated by 4.00 mm are released simultaneously. What is the speed of either at the instant when the two are 12.00 mm apart?

2. A particle has a charge of +1.30 C and moves from point A to point B, a distance of 0.190 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPE_A - EPE_B = +9.35E-4 J. Calculate the magnitude of the electric force that acts on the particle.
