Question

The principle of equivalence states that:
Options
A Gravitational force is the same as electromagnetic force.
B The gravitational mass and inertial mass of a body are equal.
Correct Answer
C All masses are equivalent in a gravitational field.
D The acceleration due to gravity is constant everywhere.
Correct Answer

Option B is the correct answer.

Detailed Explanation

explains that the gravitational mass (responsible for gravitational force) and the inertial mass (resistance to acceleration) are experimentally found to be equal. This equality is known as the principle of equivalence.

Hint

This fact explains why all objects fall with the same acceleration in a vacuum.
