Question

The three charges in the figure are at the vertices of an isosceles triangle. Calculate the work that needs to be expanded, in Joules, to bring the charges together (as shown.) Take q=5.7 μC. The length of base is b=2.30 m. The lengths of sides are s=5.80 m. The two charges at the base are negative (q1=q2=-q), the third charge is positive (q3=+q)
