Question Details My Notes Ask Your Teacher A uniform electric field of magnitude 220 V/m is directed in the positive x direction. A +10.0 C charge moves from the origin to the point (x, y) = (20.0 cm, 50.0 cm). (a) What is the change in the potential energy of the charge field system? (b) Through what potential difference does the charge move? Submit Answer Save Progress 11. Question Details My Notes Ask Your Teacher onor Society Alexander Pallagi-Honor Society Accep Alexander Pallagi - Honor Society Membership Accem Thu 10/5Explanation / Answer
+ve (10 micro C) charge will be driven by the electric field > work done by force field = increase in PE of charge
increase in PE = work done along field + work done along normal to field [as PE function is independent of path, conservative]
A)
Increase in PE = qE * 0.20 cos (o) + qE (0.50) cos 90
= 0.20 qE + 0
= 0.20 * 10*10^-6 * 220
= 4.4*10^-4 Joule
=================
B)
dW = q dV
dV = change in PE/charge = 4.4*10^-4/10*10^-6
= 44 V
