Homework Help: physics!!!

Posted by Donna on Saturday, March 22, 2008 at 9:30pm.

A small spherical insulator of mass 8.00*10^-2kg and charge +6.00*10^-7C is hung by a thin wire of negligible mass. A charge of -9.00*10^-7C is held 0.450m away from the sphere and directly to the right of it, so the wire makes an angle with the vertical. Find (a) the angle and (b) the tension in the wire.

I NEED HELP WITH THIS PROBLEM!!!!THANKS A LOT!!!!!!!
