that question seems easy but what is this new concept lol ? head to tail equi? does this have an alternate name or sth?

you dont know head to tail ?? :O the arrows form a continuous cycle

Head to tail is when there is equilibrium. xD

Its like a head meeting tail.
Draw euilibrium triangle and see you will see vectors like meeting head with tail.. Thats head to tail... Head of one vector touches tail of another vector and that tail touches head of third vector making it continuous cyccle..

Solve through dimensions.
F = kgms^-2
we have kg, ms^-2 and s.
Make equation. It will be, m * ms^-1 / s
Solve it like this if u dont remember the formula .
F = m/t * v = ma.

Let, distance travelled one way = x km

Total distance travelled = 2x km

Total time taken = x/600 + x/400 = (2x + 3x) /1200 = x/ 240 hours

Average speed = 2x / (x/240) = 480 km/h

Answer is C?

F/(5 * 1.6 * 10^-19) = 5000/ (0.8 * 10^-2)
F = 5 * 10^-13 It will go upwards as it is -ve charged.
