Chapter 3.2, Problem 3.9P

In Ex. 3.2 we assumed that the conducting sphere was grounded ( V = 0 ) . But with the addition of a second image charge, the same basic modelwill handle the case of a sphere at any potential V 0 (relative, of course, to infinity). What charge should you use, and where should you put it? Find the force ofattraction between a point charge q and a neutral conducting sphere.

Defination of voltage
At point A, 3.20 m from a small source of sound that is emitting uniformly in all directions, the intensity level is 58.0 dB. What is the intensity of the sound at A? How far from the source must you go so that the intensity is one-fourth of what it was at A? How far must you go so that the sound level is one-fourth of what it was at A?
Make a plot of the acceleration of a ball that is thrown upward at 20 m/s subject to gravitation alone (no drag). Assume upward is the +y direction (and downward negative y).
