At one point in space, the electric potential energy of a 10 nC charge is 28 μJ . If a 20 nC charge were placed at this point, what would its electric potential energy be?
Added by Bryan A.
Step 1
Step 1: Calculate the electric potential energy of the 20 nC charge using the formula for electric potential energy (U = k * (q1 * q2) / r): Given: q1 = 10 nC = 10 * 10^-9 C q2 = 20 nC = 20 * 10^-9 C U1 = 28 μJ = 28 * 10^-6 J k = 9 * 10^9 Nm^2/C^2 Show more…
