Grade 11Electric Current
Two equal metal balls are charged to 10 and -20 units of electricity. Then they are brought in contact with
each other and then again separated to the original distance. The ratio of magnitudes of the forces between
the two balls is:
(a) + 8 : 1 (b) 1 : 8 (c) +2 : 1 (d) 1 : 2
