The electrostatic force between two point charges is given by:
where
is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between them
In our problem, charge 1 is
while charge 2 is
and their distance is
r=5.0 cm=0.05 m
So, the electrostatic force between them is
And the negative sign means the force is attractive, because the two charges have opposite sign.

Explanation:
Since the force applied is parallel to the displacement of the car, the work done on the car is simply given by:
where
F = 1210 N is the force applied on the car
d = 201 m is the displacement of the car
Substituting numbers into the equation, we find:
