the wrong option: (a)
Inertial mass is a measure of difficulty of accelerating a body 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)
That 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
neighouring heavy objects but the inertial mass cannot.
