Question

A charge of `2 C` is at `(1,4 )` and a charge of `-1 C` is at `(12 ,-5)`. If both coordinates are in meters, what is the force between the charges?

Answer 1

-89.02 Mega Newton

Explanation:

Force F = `1/(4*pi*epsilon_0)*(q_1*q_2)/r^2`
Distance between charges r = `sqrt((x_2-x_1)^2+(y_2-y_1)^2`

Substituting the values we get answer as `-89.02xx10^6N`
