How do you calculate electric potential energy? To calculate the electric potential energy of a system, use the equation U_e = k(q_1q_2)/r. In this equation, k stands for the Coulomb constant, q_1 and q_2 are two charges, and r is the distance between them.What...
V(x,y,z) = electric potential as a function of x,y, and z E(x,y,z) = electric field vector as a function of x,y, and z E = -∇V = -[(∂V/∂x)i + (∂V/∂y)j + (∂V/∂z)k] Upvote • 0 Downvote Add comment Still...
If you recall that work (which has units of energy) is force times distance (F·d), this explains why this equation differs from the force equation only by an r in the denominator. Multiplying the former by distance r gives the latter. Electric Potential Between Two Charges...

ΔV=ΔPEqΔV=ΔPEqand ΔPE =qΔV The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between...
To solve part (a) you rearrange your electric potential equation to solve for Q: V=kQr⟹Q=Vrk And then plug in your numbers, keeping in mind that the radius is half the diameter: Q=Vrk=(25×103)(0.1)8.99×109=2.78×10−7C ...
