    Field strength 3

    What is the electric field strength at the vertex of an equilateral triangle with sides of 0.50m if the charges at the other verticies are +2.0x10^-5C?

    What equation would I use for this question?

    The field is the vector sum of the fields due to the two charges at the other
    vertices, and the fields strength is the norm of the vector field stength.
