I don't think that's correct. The system of equations should be: Y component: Nsinθ = mg X component: Ncosθ = Fe I understand how to do this problem now, and got the correct answer (finally). My question now is why couldn't the first equation be written as: N = mgcosθ Because according to...

Never mind, got it. I wasn't too far off in my original attempt. Nsinθ = mg is the correct equation. It makes perfect sense now. But I still don't understand why this equation: N = mgcosθ Doesn't work. Does anyone know why? According to my diagram, the two forces should be equal.

This was a homework question on Webassign. I got it wrong. But I need to know how to do this for my test on Thursday. Some classmates said that there is no reference to theta in the final answer because it's an equilateral triangle. Can anyone help me further? I'm very lost on this. Here is...

I'm still stuck on this problem. :(

Thank you for your reply. So just to be clear, the charge force has a y component, even in equilibrium? I was under the assumption that it only had an x component.

Homework Statement "Two identical beads each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless, nonconducting walls, the beads move, and at equilibrium they are a distance R apart. Determine the charge on each bead. (Use k_e for ke, g for the...
