Answer:

Key differences between gravitational force and electrostatic force are:

Origin:

  • Gravitational force is the force of attraction that two objects exert on each other due to their masses.
  • Electrostatic force is the force of attraction or repulsion that two objects exert on each other due to their electric charges.

Sign:

Gravitational force is always attractive.

Electrostatic force can be either attractive or repulsive, depending on whether the charges of the two objects are the same or opposite.

Strength:

  • Gravitational force is much weaker than electrostatic force.

Range:

  • Gravitational force is a long-range force. It acts between objects no matter how far apart they are.
  • Electrostatic force is a short-range force. It only acts between objects that are close together.

Medium:

  • Gravitational force is not affected by the medium in which the two objects are placed.
  • Electrostatic force depends on the medium in which the objects are placed.
