Hurry please!! The electric field between two parallel plates has a
magnitude of 180 N/C. The two plates are 2.5 cm apart.
Recall that the magnitude of the charge on an electron is
1.602 x 10-19 c.

How much work is done to move an electron from the
positive plate to the negative plate?

4.0 x 10-213
7.2 x 10-19 J
4.53
0 7200 J
