Help please.

A charged cork ball of mass m is suspended on a light string in the presence of a uniform electric field, as shown in the figure below. When E = (A + j) N/C, where A and B are positive numbers, the ball is in equilibrium at the angle theta. Find the charge on the ball. (U se any variable o r symbol stated above along with the following as necessary: g for the acceleration due to gravity.) q = Find the tension in the string. (U se any variable o r symbol stated above along with the following as necessary: g for the acceleration due to gravity.) T =

Explanation / Answer

a) q= mg/ (A*cot(theta) + B)

b) T= (m*g*A)/ (A*cos(theta) + B*sin(theta))
