Which law of physics states that the force between the two electric charges reduces to a quarter of its former value when the
distance between them is doubled?

SSC CGL 3rd March 2020 Shift-2
Coulomb’s Law
Correct AnswerStefan's Law
Incorrect AnswerPascal's Law
Incorrect AnswerHooke's Law
Incorrect AnswerExplanation:
- Coulomb’s Law: States that the force between two electric charges varies inversely with the square of the distance between them. If the distance is doubled, the force reduces to a quarter.
- Stefan's Law: Relates to the thermal radiation emitted by a black body, stating that the total energy radiated is proportional to the fourth power of the black body's temperature.
- Pascal's Law: Concerns fluid pressure, stating that pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid.
- Hooke's Law: Describes elasticity, stating that the force needed to extend or compress a spring is proportional to the distance it is stretched or compressed.
