(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

4 identical charges each equal to Q are placed at the 4 vertices of a regular triangular pyramid of each side equal to 'a'. Find the net electrostatic force on any one charge.

2. Relevant equations

F = kQ^2/a^2

3. The attempt at a solution

find the force due to each of the charges, resolve it into x- and y- components and hence add them..but this way i could not get the correct answer.
