3. Shown in the figure below are two point charges,Q1andQ2, and thelocation of pointP. All locations (x,y) in the figure are labelled in meters.Evaluate all of the following:Q = -2 Cμ(x=2, y=-1)(x=-1, y=0)Q = +4 CμPoint P(x=4, y=4)(a) Find the magnitude and direction of the electric field,Eat the pointP.(b) What would be the magnitude of the force on a particle of chargeq= 4μCplaced at point P.
