Two point charges are enclosed by a spherical conducting shell that has an inner and outer radius of 13.0 and 15.2 cm, respectively. One point charge has a charge of q1=8.30 μC, while the second point charge has an unknown charge q2 . The conducting shell is known to have a net electric charge of −2.40 μC, but measurements find that the charge on the outer shell is + 3.70 μC. Determine the charge q2 of the second point charge.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
