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.
