Question

Coulomb's Law equation is: FE = kq1q2/r2In this expression, FE is the electric force between charges q1 and q2 separated by distance r.Which of these sentences best describes the Coulomb's Law equation in words?A) The electric force is directly proportional to the product of the charges and inversely proportional to the distance between the charges.B) The electric force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.C) The electric force is directly proportional to the sum of the charges and inversely proportional to the distance between the charges squared.

Answer 1

Given data

*The given Coulomb's law equation is

`F_e=(kq_1q_1)/(r^2)`

From the above expression, it is clear that the electric force between the charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.

Hence, the correct option is (B)
