Hi! I have a similar problem... A rod of length L lies along the y-axis with its center at the origin. The rod has a nonuniform linear charge density lambda =a | y | , where a is a constant with the units {\rm C}/{\rm m}^{2} . Determine the constant a in terms of L and the rod's total charge...

so which equations did you use?

never mind, wrong equation! thanks

Im also having trouble with this problem. I first solved for the critical velocity (when the force normal = 0) and got sqrt(g*L/3). I then used the conservation of energy equation, 1/2(m)(vf)^2+(m)(g)(yf)=1/2(m)(vi)^2+(m)(g)(yi) Since vi = 0, and the masses cancel, I was left with...
