i'm still getting C as the answer to this one
drwl said its wrong
When a positive charge moves in the direction of the electrical field, what happens to the electrical potential energy associated with the charge?
a. increase
b. decreases
c. remains the same
d. increases sharply, then decreases
decreases - if it moves in the direction of the E vector, it is moving in the direction it wants to go.
To determine what happens to the electrical potential energy associated with a positive charge moving in the direction of the electrical field, we need to understand the relationship between electrical potential energy and the direction of motion.
Electrical potential energy is given by the equation U = qV, where U is the potential energy, q is the charge, and V is the electrical potential. The electrical potential V is created by a source charge and is the amount of electric potential energy per unit charge at a specific point in space.
When a positive charge moves in the direction of the electrical field, its potential energy decreases. This is because the charge is moving towards a region of lower electrical potential. Imagine a ball rolling down a hill - as it moves in the direction of the slope, its gravitational potential energy decreases.
So, the correct answer is (b) decreases.
