If the magnets are brought close together, they will

opposites attract

and if they are the same they will pull away from eachother

Opposite poles of a magnet attract each other, whereas like poles repel each other. When lined up with a south-seeking pole, a north-seeking pole would draw closer to that end of the magnet. However, when lined up with another north-seeking pole, the two magnets would push away from each other because their forces are not compatible

going in opposite directions

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
