Homework Help: physics

Posted by Diana on Wednesday, February 9, 2011 at 2:20pm.

Two identical small spheres of mass 2.0g are fastened to the ends of an insulating thread of length 0.60m The spheres are suspended by a hook in the ceiling from the centre of the thread. The spheres are given identical electric charges and hang in static equilibrium, with an angle of 30.0 degrees between the string halves. Calculate the magnitude of the charge on each sphere.

I've tried to solve this many different way but i cant figure it out.

so far i got Fg=mg which is 0.01962 and then i used tan 15= 0/0.01962 which equals 0.0053 but im stuck from there


any ideas please?
