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 two
changes (take an attractive force to be negative)
2.)Two charges, q1 =-16.1 μC and q2 = 11.9
μC , are located along a straight line at x = 19.5 cm and 57.5 cm
respectively. What is the electric field at a point P located at x
=...
