If the separation distance between two charges is increased, their electric potential energy

Options

  1. Amay increase or decrease
  2. Bdecreases
  3. Cincreases
  4. Dremains constant

Correct answer

A. may increase or decrease

Step-by-step solution

The electric potential energy of a system of two charges q₁ and q₂ separated by a distance r is given by: U = 1 4 ₀ q₁ q₂ r If the charges have the same sign, q₁ q₂ > 0 . As r increases, U decreases. If the charges have opposite signs, q₁ q₂ Thus, the electric potential energy may increase or decrease depending on the nature of the charges.
