## Homework Statement

A small conducting sphere of mass M is attached to a string of length L. It is at rest in a uniform electrical field of magnitude E directed due right. The sphere has a charge of Q and the string makes a 30 degree angle with the electric field.

a. Calculate the tension in the string if M = .002 kg, L = .45 M, Q = 10*10^-6 columbs

b. Calculate the magnitude of the Electric field.

c. Desrcibe what the mation of the conducting sphere would be if the string is cut

## Homework Equations

E = k(q/r^2)

## The Attempt at a Solution

a. Fg = Ft cos Theta

(.002 *10) = ftcos30

ft = .023 N

b. E kq/r^2

E = 9 * 10 ^9(10*10^-6)/.45^2 = 444444.4 N/C

c. The coundcting sphere will move down and to the right

I'm not if I got any of the parts can someone please help me out
