Aplastic stick attracting small pieces of brightly colored paper. if the stick has a positive charge, then the paper that sticks to it must have

B. The glass and the paper have different charges.

Explanation:

THIS IS THE CORRECT ANSWER edge 2020

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
