Question

If the charge is doubled, then the potential energy near it will

  1. Remain constant
  2. Increase
  3. Decrease
  4. Cannot be determined

hintHint:

U=Kq1q2/r

The correct answer is: Increase


    • Potential energy(U) is directly proportional to the product of two charges.
    • And inversely proportional to the distance(r) between them.
    • Therefore, if the charges are doubled then the potential energy becomes 4 times (means increases).
    • So, the correct option is b.
