A small charged ball with a mass of 40 g is suspended from the ceiling on a string.The ball is suspended a distance of 7.0 cm above an insulating floor.If a second small ball with a mass of 50 g and a charge of -0.60 $\mu$C is placed on the floor directly beneath the first ball and the tension in the string is 1.00 N,what is the charge on the ball attached to the string?
A)0.96 $\mu$C
B)0.55 $\mu$C
C)0.72 $\mu$C
D)1.3 $\mu$C
E)0.30 $\mu$C
