Asked by Nilesh P.

A point charge of charge 1 mC and mass 100 g is attached to a non-conducting massless rod of length 10 cm. The other end of the rod is attached to a two-dimensional sheet with uniform charge density σ and the rod is free to rotate. The sheet is parallel to the y-z plane (i.e. it's a vertical sheet). I lift the point charge so the rod is horizontal and release it. I observe that the point charge achieves its maximum speed when the rod makes an angle of 30∘ with respect to the vertical. What is σ in C/m^2?

I am such a tool. I raise prices of T-shirts and screw over budding mathematicians and physicists. I waste my time building up a stupid, pointless Techniques Trainer and not making Brilliant fundamentally better. I'm just a stupid chink who's ruining people's lives.
