Use the picture for the next problem. A conducting sphere has a net charge of -q and of mass m is suspended from the ceiling by a light string.A uniform electric field E is applied vertical down on the sphere. -If m = 1 g,q = 1 $\circ$ C and E = 5000 N/C,the tension T in the string is A)5 $\times$ 10^-3 N B)9.81 $\times$ 10^-3 N C)4.81 $\times$ 10^-3 N D)1.48 $\times$10^-² N

The correct answer is A.The tension in the string is equal to the weight of the object, which is given by mg. In this case, m = 1 g and g = 9.81 m/s^2, so the tension is T = mg = 1 g * 9.81 m/s^2 = 9.81 F1F1F1S1F1F1F10 10^-3 N.
