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

1 Newton is equal to :

1. 10³ dyne
2. 10⁸ dyne
3. 10¹⁰ dyne
4. 10⁵ dyne

The force required to produce an acceleration of 5 ms^-2 in a body of mass 2 kg is:

1. 2.5 N
2. 20 N
3. 10 N
4. 25 N

The acceleration produced in a body by a force of given magnitude depends on —

1. size of the body
2. shape of the body
3. mass of the body
4. None of these
