Approximately how much of an atoms mass is located in its nucleus? A. less than 1% B.25% C.75% D. over 99%

D.over 99%

Explanation:

Nucleus contains all of the neutrons and protons, and electrons don't weigh as much relative to the other particles.

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
