QUESTION 2 Two-point charges, q₁ = +2,0 μC and q2 = -2,0 μC, are placed 1 m from each other in a vacuum as shown in the sketch below. P is a point in the centre between q₁ and q2. 2.1Draw the electric field pattern around charge q₁, as a single charge. Calculate the magnitude of the electrostatic force between charges q₁ and q2. Calculate the magnitude of the net electric field strength at point P. 2.4 A negative point charge (-q3) is placed at a distance between the charges, q₁ and q2, so that the net force on charge q3 because of charge q₁ and q2 is equal to zero. Calculate the distance (d) where this negative point charge (-q3) should be placed.
