If it follows the 1st law of thermodynamics it would also remove heat of 314J from the food inside the refrigerator.
The displacement is the distance from the beginning point to the ending point. The time was just to throw you off. If he walks 30m due west, and then 5m due east, his displacement would be 30-5=25m to the west.
Answer
Force between two charged bodies q₁ and q₂ is given by the formula below.
F = Kq₁q₂/r²
Where k = constant
r = distance between them
F = (9.0 E9 × 1.0 E-6 × 1.0 E-6)/0.30²
= 9.0E-3/0.30²
= 9.0E-3/0.09
= 0.1 N
