Two charges are separated by some initial distance. The first charge is set in place at the origin and unmovable has a value of charge 1.02 mC. The second charge has a value of charge equal to 1.91 mC and mass 750g. When the second charge is allowed to move it is propelled forward from rest with an initial force of 49 Newtons. Using conservation of energy find the speed of the particle in m/s when it is 64 meters away

Two particles of equal mass 10 mg and equal charge 35 nC are brought from an infinite distance apart until they are only separated by 2 x 10 -10 meters. The particles are released from rest. What speed will they have when they are very far apart from one another?

A particle with electric charge -2 nC is located a distance of 1 cm from another particle with charge +4 nC resulting in a potential energy of -7.2 micro J.  Another set of two particles has charges of +4 nC and -8 nC separated by 2 cm. What is the potential energy of this other system?

A particle with a charge of 8.30 nC is in a uniform electric field directed to the left. Another force, in addition to the electric force, acts on the particle so that when it is released from rest, it moves to the right. After it has moved a distance of 5.00 cm, the additional force has done an amount of work equal to 7.90×10-5 J and the particle has kinetic energy equal to 3.90x10-5 J.
