A point charge distribution consists of a point charge Q1= 5 microcoulombs atcoordinates (-4,2)m and a point charge Q2 = -5 microcoulombs at (4,2)m. Thefield point is at (0,5)m. A charge Q=-10 micro coulombs is brought in frominfinity by an external source and placed at the field point.a) Find the distance and unit vector from source to field point for charge 1and charge 2b) Find the work done by the external source in bringing the charge in frominfinity and placing it at the field pointc) Express the total force acting on the charge Q placed at the field point in"I, j" format

Let P be the observation point and the charges q1 and q2 be placed at the positions r1 and r2…
