I was wondering if a non-English version of MS Office can run smoothly in the English version of WinXP... with the taskbar buttons in the program properly displayed, etc. Thanks for answering :)
A parallel plate capacitor has charge Q and plates of area A. What force acts on one plate to attract it toward the other plate?
It's F = Q^2 / (2*8.854e-12*A) ... something to do with the electric field divided in 2? Wondering why there's a 2 in the denominator... thanks :)
Two large parallel vertical conducting plates separated by distance d are changed so that their potentials are (+V sub 0) and (-V sub 0).
A small conducting ball of mass m and radius R (where R<<d) is hung midway between the plates.
The thread of length L supporting the ball is a...
Two small spheres of mass m are suspended from strings of length L that are connected at a common point.
One sphere has charge Q, the other has 2Q.
The strings make angles (theta1) and (theta2) with the vertical.
(a) How are theta1 and theta2 related?
(b) Assume theta1 and theta2 are...
Identical thin rods of length (2a) carry equal charges +Q uniformly distributed along their lengths.
The rods lie on (along) the x-axis with their *centers* separated by a distance b > 2a.
(Left rod from x=-a to x=a, right rod from x=b-a to x=b+a)
Show that the magnitude of the force...
