Question

two charged particles having charge 2 X 10-8C each are joined by an insulating string of length 1 m and the system is kept on a smooth horizontal table.find the tension in the string

Answer 1

Answer:

Two charged particles having charge 2.0 x 10-8 C each are joined by an insulating string of length 1 m and the system is kept on a smooth horizontal table. ... (b) Force on the second sphere due to the first is same, i.e., 0.2 N because the charges in action are same and force is attractive as charges are unlike in nature.
