consider the positive ion is moving under the influence of both electric and magnetic fields. how do you distinguish the effects of the two fields

kinetic

i'm so sorry if this is wrong i'm only in 6th grade xd

6 cos 34, 6 sin 34 trig

if they have a finite resultant

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
