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

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

Newton's first law of motion defines force :

1. quantitatively
2. qualitatively
3. both (a) and (b)
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
