Question

Which of the following statements is wrong ?

• 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. The gravitational mass and inertial mass are equal is an experimental result.
• C. The acceleration due to gravity on earth is the same for all bodies 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

The gravitational mass of proton is equivalent to its inertial mass. Hence, option (4) is wrong.
