Potential Energy of a Charge

jeudi 30 janvier 2014

1. The problem statement, all variables and given/known data

The electric field in a particular region of space is found to be uniform, with a magnitude of 700 N/C and parallel to the +y direction.



(a) What is the change in electric potential energy of a charge [q = 6.5 mu or micro CC if it is moved from [(x, y) = (20 cm, 45 cm)] to [(5 cm, 30 cm)]? Answer in mJ.



(b) What is the change in electric potential energy if the charge is moved the same distance along the x axis? Answer in mJ.



Are my attempts correct?





2. Relevant equations

q*E*d







3. The attempt at a solution

(a) (6.5e-6)*700*(.015) = .06825 mJ

(b) (6.5e-6)*700*.015*√(2) = .09652 mJ
