a)
V = electric potential = - 70 m V = - 0.07 volts
q = charge
r = distance from the charge = 7 m
Electric potential is given as
V = k q /r
- 0.07 = (9 x 109) q/(7)
q = - 5.44 x 10-11 C
b)
Q = 2e = 2 x 1.6 x 10-19
electric potential energy is given as
U = Q V = (2 x 1.6 x 10-19) (- 0.07) = - 2.24 x 10-24 J

A point charge with charge q1 = +5.00 nC is fixed at the origin. A second point charge with charge q2 =-7.00 nC is located on the x axis at x 7.00 m. 1) Where along the x axis will a third point charge of q = +2.00 nC charge need to be for the net electric force on it due to the two fixed charges to be equal to zero? (Express your answer to three significant figures.)
There is an electric potential energy (EPE) between a charge Q sitting at the origin and a point charge q located at r: EPE = kQq/r, which, unlike the electric force, is a scalar quantity. The electric potential V produced by Q at r is equal to the potential energy of a unit charge at r. Based on these two pieces of information, one can conclude that the magnitude of V at r due to Q is Question 2 options: 1) kq/r2....
