A car has a displacement of 500 Km [E 100 N] and then another of 100 Km [W 300 N]. If it completes the trip in 2h, determine the average velocity in Km/h.

empty space could also be a simple vacuum

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
