Question 18 2 pts What distance must separate two point charges of 68.1 nC in order to have a force of 1.16 N between them? Please give the distance in mm. Question 19 2 pts A pair of point charges exert a 27.8 N force on one another. What force will they experience if we increase the distance between them by a factor of 2? Question 20 2 pts Calculate the attractive force between a glass rod with a +0.707 uC charge and a silk cloth with a -0.564 uC charge, given that they are 12.1 cm apart, and using the approximation that they act like point charges? Please express the force in mN (1 mN = 10-3 N)
