Question

Consider the interaction of two particles. Under what conditions will the interaction of those two particles have a positive potential energy?

a) The potential energy will be positive if both particles have the same sign charge
b) When they are opposite charges and close together
c) When they are opposite charges and far apart
d) When they are like charges and far apart

Answer 1

The potential energy of interaction between two particles can be positive under certain conditions.

Step-by-step explanation:

The potential energy of interaction between two particles depends on the charges of the particles and their separation. If the two particles have the same sign charge, the potential energy will be positive. If the particles have opposite charges and are close together, the potential energy will be negative. However, if the particles have opposite charges and are far apart, the potential energy will be positive. Similarly, if the particles have like charges and are far apart, the potential energy will be positive as well.
