Exercise 1 Three charges A, B and C are placed in a straight line and in this order. The charge of A is twice that of C and has a value of 40.0nC. B carries 6.25 x 1011 electrons. A is 5cm from B and 8.5cm from C. a.) Show that the charge of B is -100nC. b.) Calculate the resultant force exerted on C due to A and B. c.) Show, without any calculation, that the resultant force on C cannot be zero, if it is now placed between A and B.
