In respect of the difference of the gravitational force from electric and magnetic forces, which one of the following statements is true?
General KnowledgePhysics
- AGravitational force is stronger than the other two
- BGravitational force is attractive only, whereas the electric and the magnetic forces are attractive as well as repulsive.
- CGravitational force has a very short range
- DGravitational force is a long range force, while the other two are short range forces.
Explanation
Gravitational force is attractive only and is far weaker than the electromagnetic forces; electric and magnetic forces can each be attractive or repulsive, and both are long-range forces. The true statement is B.
