Oh, ok. I never thought of a neutral conductor in that way, but that makes a lot of sense! Thank you!

Why should the force on a point charge always be toward a neutral conductor? I know this is a simple concept, but I'm having trouble grasping it. Any ideas? Thanks!

Oh okay, now I understand. Thank you for the help!

Not quite. Do you mind explaining a little further?

Homework Statement A square insulating sheet whose sides have length L is held horizontally. The sheet has a charge of Q spread uniformly over its area. a) Estimate the electric field at a point located a distance r_2 above the center of the sheet. Use the appropriate approximations based on...

Homework Statement A point charge, q, is at the center of an insulating hollow sphere with inside radius, a, and outside radius, b. The spherical shell has charge per unit volume, rho. You may assume that q and rho are positive. Using Gauss' law, find the magnitude of the electric field...

Oh okay, that makes sense. Thanks for all the help!

Oh okay, I realized that I was just plugging in the wrong numbers, but now I have the right answers. Thank you! Although, I'm still confused on part D. I'm not sure what equation to use. Any ideas?

Thanks for the welcome and for the help. But I'm not exactly sure what you mean by the two different approaches. Could you maybe clarify a little bit?

An experiment is performed in deep space with two uniform spheres, one with mass 30.0 kg and the other with mass 109.0 kg. They have equal radii, r = 0.20 m. The spheres are released from rest with their centers a distance 42.0 m apart. They accelerate toward each other because of their mutual...
