Three equal negative charges, of magnitude 6Coulombs are situated at the vertices of an equilateral triangle, with a length of side equal..?
...to 7.2. A small test charge of 0Coulombs is placed in the exact centre of the triangle. What is the magnitude of the resultant force on the test charge?
please show step by step workings

The force is zero, easily explained two ways:
1) the test charge isn't a charge at all -- it's 0 coulombs. Therefore it can feel no electrostatic force.
2) At the center we have symmetry due to the charges arranged at the corners. ANY charge at the center would feel no net force.
Hope this helps!
