Apoint charge q is located in vacuum at (d, 0, 0), a distance d from the yz plane that is the surface of a homogeneous dielectric with dielectric constant ke occupying all space to the left of this plane, that is, for all negative values of x. find: (a) the surface charge density of bound charges as a function of a distance r from the point charge q; (b) the total bound charge on the surface of the semiconductor

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
