1.) Two charges, q1 = -16.5 μC and q2 =13.5 μC , are located at (x,y) = (12.4, 21.2) cm and (19.6, 24.0)cm respectively. Find the electrostatic force between these twochanges (take an attractive force to be negative)
2.)Two charges, q1 =-16.1 μC and q2 = 11.9μC , are located along a straight line at x = 19.5 cm and 57.5 cmrespectively. What is the electric field at a point P located at x= 35.1 cm?[Consider a field directed to the right as beingpositive]
3.) Two plates, separated by a distance of 15.0 cm, have apotential difference of 3.40×103 between them, with thepositive plate on the left. Calculate the electric field betweenthe plate, taking as positive a field that points to the right.
4.) Two charges, q1 = 34 μC and q2 = 40μC, are located along a straight line at x = 34 cm and 64 cmrespectively. Where along the x-axis should a third charge ofq3 = -11 μC be located such that the net force on thischarge is zero.
