Problem 2P
A uniform electric field of magnitude 4.1 × 105 N/C points in the positive x direction. Find the change in electric potential energy of a 4.5-μC charge as it moves from the origin to the points (a) (0, 6.0 m); (b) (6.0 m, 0); and (c) (6.0 m, 6.0 m).
ANSWER:
Step 1 of 3:-
Here we have to find the change in electric potential energy of a charge as it moves from the origin to the given points.
We know that, the electrostatic potential energy is,
---------------(1)
It can also be written as,
----------------(2)
As,
a)
The electric field points in the positive x direction and the charge moved towards y direction.
The electrostatic potential energy will remain constant.
