Two charges of q₁ = 1.9 μC and 92 figure below. 9₁ d P d = -2.8 µC are d = 0.64 m apart at two vertices of an equilateral triangle as in the 9₂ (i) (a) What is the electric potential due to the 1.9-µC charge at the third vertex, point P? V (b) What is the electric potential due to the -2.8-µC charge at P? V (c) Find the total electric potential at P. V (d) What is the work required to move a 4.0-μC charge from infinity to P? J
