Hi, I had three problems to do that are multiple choice, here they are and my answer with them. Please tell me if some are wrong.
1. Spherical conductor of radius R carries char +Q, which statement(s) are correct?
I. Electric field outside the surface of the conductor is the same as the...
Hi, I don't want help solving this problem, just a method to complete it without using calculus. Here it is:
A thin glass rod is bent into a semicircle of radius r. A charge +q is uniformly distributed along the upper half, and a charge -q is uniformly distributed along the lower half. Find...
Okay, here is the source of my confusion about this problem. First it says find the linear acceleration of mass M, then the following question asks me to find the frictional force acting on the disc. But don't I need to find the frictional force before I find the acceleration?
I'm sorry I should have been clearer. fs is the frictional force, except on my paper my teacher said that fs does not equal uMGcos(theta), which is the source of my problem. He says fs equals 1/2Ma, which is where I got a = 2fs/M from.
Sum of the torques = I(angular acceleration)
fsR =...
I'm stuck on a miniquestion in my HW that is hindering the entire problem, so here it is.
A disc of mass M, radius R, Icm =1/2MR^2 is rolling down an incline dragging a mass M attached with a light rod to a bearing at the center of the disc. The friction coefficients are the same for both...
Hi, I'm stuck on two physics HW questions, and I'd like some help. Here are the questions and my (probably incorrect) work on them:
1) A disc of mass M, radius R, Icm = 1/2MR^2 is rolling down an incline dragging a mass M (block) attached with a light rod to a bearing at the center of the...
