Two ice skaters on ice push away from each other. What will be the effect of the forces of their pushing each other if their masses are different? 

If the masses are different, the lighter ice skater will accelerate faster than the ice skater with more mass.

Explanation:

+15-35=-20

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
