E) If assertion is false but reason is true.
Correct Answer: A
Solution :
According to Newton?s second law of motion \[a=\frac{F}{m}\] i.e. magnitude of the acceleration produced by a given force is inversely proportional to the mass of the body. Higher is the mass of the body, lesser will be the acceleration produced i.e. mass of the body is a measure of the opposition offered by the body to change a state, when the force is applied i.e. mass of a body is the measure of its inertia.
