Ok I worked out the constant and it has units N/m (which made me smile, finally the end to a problem that's been troubling me for hours!) Thank You!

For the second question I must solve for frequency is it correct to solve for it like this? f = \frac{1}{2\pi }\sqrt{\frac{Constant I found }{m_{e}}}

Sorry the convention confused me E field lines are in the direction where a positive test charge would move so it will move opposite or inwards

Also outwards?

It would be outwards if it is positively charged.

I'm sorry they called the charge of the cloud e which made me think negatively charged. However the e-field is only constant at a certain distance r why would the force restore it to equilibrium?

Ok so the gaussian surface at an arbitrary distance r would have E-fields pointing inward which means the electrostatic force works opposite the motion of the electron? Is this a valid statement for why I can make the addition of a negative sign?

That's all my work so far not sure how to prove SHM.

Ok so it will be 2e since we need to add the point charge and total enclosed charge. And all SHM motions take the form of F= -(constant)r which is what I have minus the negative. But that's a critical component because it's supposed to be a restoring force, no?

This forum is so helpful! Every time I post a question there's always a response!

Homework Statement According to an old model due to JJ Thompson, an atom consists of a cloud of positive charge within which electrons sit like plums in a pudding. THe electrons are supposed to emit light when they vibrate about their equilibrium positions in this cloud. Assume that in the case...

OK I'm obviously very new at writing things out not sure why things are striked out and the subscripts did not go in properly. I'll correct them next time. I believe it is still easy to read, however.

Homework Statement Given: The friction between the block with mass 11kg and the wedge with mass 22kg is 0.48. The surface between the wedge with mass 22kg and the horizontal plane is smooth (without friction). The [A][/g] = 9.8m/[/2]. A Block is released on the incline plane (top side of...
