A uniform electric field of magnitude 210 V/m is directed in the positive x dire

Question

A uniform electric field of magnitude 210 V/m is directed in the positive x direction. A +12.0 wC charge moves from the origin to the point (x, y)-(20.0 cm, 50.0 cm). (a) What is the change in the potental energy of the charge field system? 5.4E4 Your response is within 10% oi the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least tour-digit accuracy to minlmize roundoff eor. (b) Through what potential difference does the charge move?

Explanation / Answer

U =- q E delta x ( as the electric field exists only along x axis)

U = - 12 x 10^-6 (210) (0.2) = -504 x 10^-6= -5.04 x 10^-4 J
