Maxing out on any given exercise will essentially require you to form?

c.the charges if the proton and electron and gravity

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

i think its c if i'm wrong

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
