Magnetism as a relativistic phenomenon.
Why is v- greater than v+? Please provide a complete
explanation.

of magnetism.4 Suppose you had a string of positive charges moving along to the right at speed v. I'lI assume the charges are close enough together so that we may regard them as a continuous line charge λ. Superimposed on this positive string is negative one, proceeding to the left at the same speed v. We have, then,...

1. Image charges in sphere We have two charges of magnitude +Q seperated by a distance of 2d, see drawing. a) Find a grounded conducting sphere (potential set to zero) with radius R, where R is the minimum radius needed to neutralize the repulsion from the two charges on each other. Hint: Try to reverse engineer the idea of image charges for a sphere which was discussed in the lectures. Place image charges and find an expression for the force....

Magneticd fields..
Im kinda lost in this sample problem im trying to study..
could someone pls clarify my questuon i wrote in green..
My question is why they used that formula or can u relate that
to the formula i shown to u from my book. Whyvthey ignore that part
pf the formula for this problem??
Also i dont understand the limit for 1/r could someone pls
help explain..
Any helpful help would be appreciated..

need help solving for the charge “q”. My professor says it’s just
algebra but it seems to be challenging. I added photos of the lab
and a free body diagram for reference.

3.1 Pre-lab In the lab on electric potential and electric field lines, you noted that charged par- ticles produce electric fields and these electric fields, in turn, act on charged par- ticles. However, you then proceeded to produce an electric field geometry using conductors held at a particular electric potential. What happened to the electric charges? Electric charge and electric potential are closely related to each other. Putting charge on a conductor raises its electric potential. It is usually much...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

Bob places a neutrally charged conducting ball next to a large, charged plate. The conducting ball is weakly attracted to the plate. What is the net charge on the plate? 1. a) Positive b) Negative c) Neutral (i.e., zero charge) d) Either positive or negative, but it is impossible to tell which A +1 C charge is at the origin, and a second +1 C charge is at position (x,y)-(2 m, 0). How much work is required to move the...
