Mrs. Davey pushes a 2-kg Physics Book horizontally against the wallIf the coefficient of friction between the book and the wall is 0.15, with what minimum force must Mrs. Davey use to keep the book from sliding down the wall?

be subject to a force andchange its motion

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

inverse v=i*r
