Imagine that distance d is much greater than the length of the wire. intuitively, what should the magnitude of the electric field at point p be in this case? express your answer in terms of some or all of the variables q and d, and the constants π and ϵ0. the variable l should not appear in your answer.

the answer is b, have negligible mass

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

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
