/sci/, i need help wit dis shiz We have an equilateral triangle where each side is 10cm. In each angle we have a charged dot with +5nC (5*10^-9 C). Calculate the size and direction of the total force working on one of the charges. (I hope my english-translation of the problem makes sense.)

We have an equilateral triangle where each side is 10cm.
In each angle we have a charged dot with +5nC (5*10^-9 C).
Calculate the size and direction of the total force working on one of the charges.

(I hope my english-translation of the problem makes sense.)
