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.
Porcine = of, affecting, or resembling a pig or pigs
Equine = of, relating, or affecting horses or other members of the horse family
Ursine = of, relating to, or resembling bears
Feline = Of, relating to, or affecting cats or other members of the cat family
Your answer is option "D. feline"

Answer:
I don't know sorry For this question
Answer:

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:
