Hello, I was looking over my notes and I was trying to figure out when we integrate Q enclosed when Q = ρ*d(volume). If there's one thing I've learned from physics II you only integrate when a field is non-uniform. I'm just wondering how we know when it's uniform (usually the problem will tell...

I'm not quite sure how to set up this equation. If the total potential is zero then the sum of the potentials should be zero. This would mean the potential of charge Q at a certain point, -3Q at that point and +3Q would equal zero at this/these point(s). The charges are known, the total...

Wouldn't the charge induced simply be +Q? Sorry, I mistyped again. I meant 1kQ/R is the voltage induced on the inner radius of the thick conducting shell by the point charge.

It's the charge of the particle on the inner radius of the thick conducting shell. That's what I thought at least.

I miswrote it, it should be 1kQ/R but I don't think the k constant matters as much. 1kQ/R to me just means 1 volt.

Homework Statement A particle carrying charge +q is placed at the center of a thick-walled conducting shell that has inner radius R and outer radius 2R and carries charge −3q. A thin-walled conducting shell of radius 5R carries charge +3q and is concentric with the thick-walled shell. Define V...

Homework Statement A positively charged nonconducting solid sphere of radius R has a nonuniform volume charge density given by ρ0 for r≤R/2 and given by 2ρ0(1−r/R) for R/2 ≤r≤R, where r is the radial distance from the sphere center.Part A Determine the charge q on the sphere in terms of ρ0 and...

This was before we learned of potential difference. We just learned about voltage (past high school level physics) today. Thanks :)

Thank you so much!

N⋅m2/C Thank you.

I'm thinking since this is not a closed surface I should instead simply use Flux = E*A so E = the given amount 150 and A = pi*(.2)^2 giving the amount 18.84 for flux. I think this is correct however I'm down to only 3 tries. Do you think this is instead correct?

Homework Statement [/B] A butterfly net hangs from a circular loop of diameter 400 mm . You hold the loop horizontally in a region where the electric field is 150 N/C downward, as shown in (Figure 1) . What is the electric flux through the net? Homework Equations k = 9E9 N E = kq/r2 Flux = Q...

Thank you so much! The second part of your comment really helped me. I've noticed how you're consistently on this forums helping out people whether it comes to high level physics or high school stuff and it's really well appreciated.

I trying to understand why D = (a^2/2^2 + b^2 /2^2). To me it seems as if it should simply be D = (a^2 + b^2)

Homework Statement The moment of inertia for a perpendicular axis through the center of a uniform, thin, rectangular metal sheet with sides a and b is (1/12)M(a2 + b2). What is the moment of inertia if the axis is through a corner? The answer is given as this was a powerpoint lecture and it...
