(c) Force between two protons is same as that of between proton and a positron. As positron is much lighter than proton, it moves away through much larger distance compared to proton.

We know that work done = force (distance). As forces are same in case of proton and positron but distance moved by positron is larger, hence work will be more.

This is a short answer type question as classified in NCERT Exemplar

Energy given by 1 lit of petrol = 3 $\times {10}^{7}J$

Efficiency of the car engine=0.5s

Energy used by the car = 0.5 $\times 3\times {10}^7=1.5\times {10}^7$

Total distance travelled s = 15km = 15 $\times {10}^{3}m$

If f the force of friction= E= f $\times s$

1.5 $\times {10}^7$ = f $\times 15\times {10}^3$

F= $\frac{1.5\times {10}^7}{15\times {10}^3}={10}^{3}N$

F= 1000 N
