Question

How does the electrical potential energy between two positively charged particles change if the distance is increased by a factor of 2?

a. it is reduced by a factor of 2
b. it is increased by a factor of 2
c. it is increased by a factor of 4
d. it is reduced by a factor of 4

Answer 1

Answer: it is increased by a factor of 2

Step-by-step explanation:

Answer 2

A. it is reduced by a factor of 2

Step-by-step explanation:

• Electrical potential energy decreases as the distance between charged particles increases.
• Electric potential is the amount of potential energy per unit charge.

• Therefore; electrica potential energy is given by the formula;

V(r) = kq1q2/r

• From the equation, the electrical potential energy is inversely proportional to the distance of separation between charged particles, therefore if the distance increases by a factor of 2, then the electrical potential energy is reduced by a factor of 2.
