The physics of electric potential energy at one corner of a triangle.

Two charges, q1 = +5.0 ìC and q2 = -2.0 ìC are 0.50 m apart. A third charge, q3 = +6.0 ìC is brought from infinity to a spot 0.50 m from both charges so that the three charges form an equilateral triangle.

a) Determine the total electrical potential at the location of q3 created by the charges

q1 and q2.

b) Determine the change in electric potential energy in bringing the charge q3 to this

location.

c) Determine the work required to bring the charge q3 to the location described
