How do you calculate the total electric potential energy ( $U_e$ ) for multiple charges?

Sum all individual $U_e$ values, considering positive and negative signs.

How do you calculate the electric potential (V) of multiple charges?

Sum the individual potentials due to each charge.

How to calculate the change in voltage ( $Delta V$ )?

Use the formula: $Delta V = V_b - V_a = \int_a^b -E cdot dl$

How do you calculate the total electric potential energy ( $U_e$ ) for multiple charges?

Sum all individual $U_e$ values, considering positive and negative signs.

How do you calculate the electric potential due to multiple charges?

Sum the individual electric potentials contributed by each charge.

Describe the process of finding the change in voltage ( $\Delta V$ ) using an integral.

$\Delta V = V_b - V_a = \int_a^b -E \cdot dl$ . Integrate the negative dot product of the electric field and displacement from point a to point b.

What is the effect of moving a charge along an equipotential line?

No work is done, and the electric potential energy remains constant.

What happens to the electric potential (V) as the distance (r) from a point charge approaches infinity?

The electric potential (V) approaches 0.

What is the effect of doing work by the electric field on a charge?

The electric potential energy of the charge decreases.

What is the effect of doing work against the electric field on a charge?

The electric potential energy of the charge increases.
