MCQ
Which among the following is false?
  • A
    Coulomb force is a central force.
  • B
    The force between two charges depend on the medium between them.
  • ✓
    Coulomb force is a weak force.
  • D
    The net force on a charge is the vector sum of the forces acting on it due to several other charges.
✓

Answer

Correct option: C.
Coulomb force is a weak force.

Coulomb force is a strong force. It can be shown that the Coulomb force between two electrons is $10^{43}$ times than gravitational force. All the other options are basic properties of Coulomb’s Law.
