If the charge is the charge voltage has two mutual sucking size 200 10 cm apart when dai Zhong values of voltage between these two ages to put away each 5 cm (1 Newton = 105 dai)
If the charge is a charge with the electric shock each other with 200 Convention on the distance of 10 cm. Determine the force between charged both when placed at 5 cm. (1 Newton = 105 Convention).
If the charge is the electric charge absorption has two points each other size 200 dyne when were apart, 10 cm. Find the value of the force between two charged when put away 5 cm (1 N = 105 dyne).
