I have been working on this problem all night. I am not looking for a numberical answer, just help with the equations. A charged cork ball of mass 1.15 g is suspended on a light string in the presence of a uniform electric field.(adsbygoogle = window.adsbygoogle || []).push({});

When the electric field has an x component of 3.05E+5 N/C, and a y component of 4.81E+5 N/C, the ball is in equilibrium at q = 35.7o. Calculate the charge on the ball.

I can not figure out how to find the electric field using the x and y components. One I figure that out I can get the problem.

Any help would be appreciated.

Thanks!
