If the spheres are now brought close to each other, but do not touch, describe how the charges will be distributed on their surfaces.

it would be distributed uniformly.

Explanation:

charge carriers in conductors are free to move around and that charge on a conductor spreads itself out on the surface of the conductor.

When the two conducting spheres are brought together to touch, it is as though they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres. When the spheres are moved apart again, each one is left with half of the total original 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
