Can someone help me with this problem please from general physics 2.

The figure shows two tiny 5.0-g spheres suspended

Answer 1

Answer #1

Option (B) 89nC is the correct answer.

Explanation:

Here, resolving the force component, you will get -

mg sin theta = Eq cos theta

=> q = mgtan theta/E

Now, from the expression, E = [1/(4*pi*epcilon)]q/r^2 and putting the values -

We gert, E = 39505 N/C

Therefore, q = (5x10^-3x9.81xtan4.1) / 39505 = 89x10^-9 C = 89 nC
