Consider a spherical volume of radius R filled with a uniform electric charge density p(rowe)
a) Use Gauss' law to calculate the electric field E in the interior of the spherical charge
b) Use the expression for the electric field to derive an expression for the Maxwell stress tensor...
Did you get that from Analytical Mechanics by Fowles...the exact thing is in there...wow.. a lot of people on here are using that one..the same book that I am using!
I understand most of what you said except for this
Does that vector pass through the some one point for all t? If so, that is a "central force field".
Can you explain that again?
Also, I ahve never sen that queation before. IS it derived somewhere on the net?
Are you saying that the polar equation is r^(-5)? I need some help here desparately.
I know about the angular momentum and torque but am not sure what the outline of the solution will look like. Maybe that is where I need some explanation.
Also, I am not particularly sure about the explanation that cookie master gave cause it makes sense to me. He said to try and find a...
A particle moves on a circular orbit in a central force field. The origin of the force lies on the circle.
Find the polar equation of the orbit.
I am confused as to how to set up this question.
A particle moves in the spiral orbit given by r = a*theta^3. If theta(t) = c*t^3, determine whether the force field is a central one. I have studied the derivation of the orbital equation for a central force field but this says to determine that! I am desparate for help here folks, I am quite...
