Calculate force on point charges

[Shivansh Mathur]

Find the force on 2Q and -Q/22. Force between two point charges is given by : F = k.q1.q2 / d[2][/SUP]

The Attempt at a Solution

To find the force on 2q, I added the charges on left side and then calculated it using the formula.

But how do we do it for -Q/2.

Please guide me. Thanks

Same way. But we keep in mind that forces are vectors, with a magnitude and a direction.

Yeah. Thanks
