Question: In the Figure shown, a small, nonconducting ball of mass m= 2.0 mg and charge q= 3.0 x 10-$C (distributed uniformly through its volume)

In the Figure shown, a small, nonconducting ball of mass m= 2.0

In the Figure shown, a small, nonconducting ball of mass m= 2.0 mg and charge q= 3.0 x 10-$C (distributed uniformly through its volume) hangs from an insulating thread that makes an angle e= 30.0 with a vertical uniformly charged nonconducting sheet as shown in the Figure. Considering the gravitational force on the ball and assuming the sheet extends far vertically and into and out of the page, the surface charge density o of the sheet is Hint: Permittivity of free space c=8.85 x 10 12 C/N.m2, nC=10C. m, 4 a) 6.68 nC/m2 e) 9.24 nC/m2 b) 8.09 nC/m2 d) 7.51 nC/m2.
