An astronaut is in outer space and throws a ball. After she releases the ball:
Draw a free body diagram of the ball.
b. What is the net force on the ball?
c. If the ball was moving at 10 m/s right as she
a.

it's a b and

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
