Question

Choose the wrong option.

• A. Inertial mass is a measure of difficulty of accelerating a body by an external force whereas the gravitational mass is relevant in determining the gravitational force on it by an external mass.
• B. That the gravitational mass and inertial mass are equal is an experimental result.
• C. That the acceleration due to the gravity on Earth is the same for all bodies and is due to the equality of gravitational mass and inertial mass.
• D. Gravitational mass of a particle like proton can depend on the presence of neighbouring heavy objects but the inertial mass cannot.

Answer 1

Answer: (D)

Gravitational mass of a particle like proton can depend on the presence of neighbouring heavy objects but the inertial mass cannot.

Answer 2

According to the principle of equivalence the gravitational mass of a body is equal to its inertial mass.
