A student applies a force of 85 N to the back of a classmate who is sitting in the teachers rolling chair. what is the acceleration of the student and chair if their mass is 75 kg?​

i wanna say it’s between b and d, leaning more towards b.

your answer is, orbit around the nucleus

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
