Question

Choose the incorrect statement from the statements given:

  1. Electric force may be attractive or repulsive in nature
  2. The electric force depends upon the medium between the charges
  3. The electric force is the weakest fundamental force in nature
  4. The electric force depends on the distance between the charges

Hint:

Gravitational forces – Gravitational force is the force of attraction which any two masses in the universe feels towards each other. This is the weakest of all.

The correct answer is: The electric force is the weakest fundamental force in nature


    The electromagnetic force is a very strong, long-range force with unlimited range that acts between any two objects possessing an electric charge. It is the fundamental interaction that binds electrons to nuclei to form atoms and binds atoms together in molecules and solids.
