Question

Two charges of `-1 C` and `2 C` are at points `(-9,0,8)` and `( 3,-6,7)`, respectively. Assuming that both coordinates are in meters, what is the force between the two points?

Answer 1

Follow the Explanation

Explanation:

`dist(r) = sqrt((x_1-x_2)^2+(y_1-y_2)^2+(z_1-z_2)^2`
Calculate dist using above formula putting the given values.
`r^2` will be 181 `m^2` . Then apply following formula to calculate
the force

`F= 1/(4piepsilonr^2)qQ`
