Two particles with charges +2e and -8e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 6.89 x 10-11 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?

Two particles with charges +8e and -6e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 6.57 x 10-12 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?
Two particles with charges +8e and -6e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 6.60 x 10-10 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?
Two particles with charges +5e and -5e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 5.42 x 10-11 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potential energy? HELP!!
Two particles with charges +5e and -5e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 7.71 x 10-10 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?
Two point charges Q1 = +3.2 ?C and Q2 = +3.6 ?C are initially separated by 1.0 m and held fixed. The charges are then released, and both move in response to the electric force between them. What is the sum of the kinetic energies of the two particles when they are very far apart?
Put two point charges on the same x (or y) axis, some distance apart, but fixed in place (immovable). One is positive, the other is negative, but their magnitudes are unequal. No other charges are nearby these two. There are two positions the same x (or y) axis where the net electric potential due to these two charges is zero. The question below can be answered for either position, but doesn't have to be answered for both. Question: choose one...
An infinite plane of charge has surface charge density 0.2 c/m2 Ho far apart are the equipotential surfaces whose potentials di e「 10 eBook + -13 points Tiper623.Р.065 My Notes Ask You Three point charges are on the x axis: g1 is at the origin, 92 is at x = +3.50 m, and 93 is at x = +5.00 m. Find the electrostatic potential energy of this system of charges for the following charge values. (Assume the potential energy is...
Two like charges a distance r apart have a positive electric potential energy. Conversely, two unlike charges a distance r apart have a negative electric potential energy. Explain the physical significance of these observations.
a. Two identical positive point charges Q are initially spaced a distance d apart. If they are released from rest, how fast will they be moving when they are very far away from each other? Assume they have identical masses m, and express your answer in terms of the given quantities and the Coulomb constant k. b. Evaluate the speed numerically if Q = 0.71 ?C, m = 1.13 mg, and d = 5.5 cm.
Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm
