an office uses six bulbs of 25 w and 2 fans of 100w each for 10 hrs and open all day of the week if the cost is 5 k per unit how much does it cost for a month

because if the tool that you are using is not balanced it there would be false mass.

that the claims meet official rules.

don't misinterpret the claims

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
