For a given force F, the graph plotted for acceleration against mass is:

According to Newton's second law, the acceleration produced in a body is:

1. inversely proportional to the force applied on it
2. directly proportional to the force applied on it
3. not dependent on force
4. none of these

The mathematical expression of Newton's second law of motion is:

1. F = m x v
2. F = m x a
3. F = pv
4. F = m/a

Newton's first law of motion defines force :

1. quantitatively
2. qualitatively
3. both (a) and (b)
4. none of these
