Question

Which of the following can never be a push force?

• A. Electrostatic force
• B. Magnetic force
• C. Muscular force
• D. Gravitational force

Answer 1

The correct option is D Gravitational force

Electrostatic force between two like charges is a repulsive force. This means that the charges oppose each other by applying push force.
Similarly, the magnetic force between two like poles is a repulsive force. This means that the poles oppose each other by applying push force.
Muscular force is the force which is exerted by the muscles of our body. Thus it can be a push or a pull depending upon our own will.
Gravitational force on the other hand can never be a push force. It is a pull force which the earth applies on all the objects, towards its centre.
