Imagine that two charged balls placed some distance apart strongly attract each other. Now imagine placing a pane of glass halfway between the two balls. Will insertion of this glass increase or decrease the magnitude of force that each ball feels, or will it have strictly no effect? Use diagrams to explain your reasoning carefully.

Two speakers are placed next to each other, a distance d = 0.328m apart. They are driven by the same frequency generator. The combined sound wave is measured along a straight line parallel to the plane of the speakers, which is at a distance D= 3.89m from the speakers. The m=3-order maximum is at an angle theta=9.12 degrees. Calculate the wavelength of the sound wave.

Two balls are separated by an some vertical distance h (in meters) from each other. The first ball is thrown down with an initial velocity voi = -3.0 m/s and the other one is thrown up from the ground with an initial velocity vo2 = 3.0 m/s at the same time the other is thrown. How far, in meters, must they be separated so they hit the ground at the same time?

1. Two small, charged plastic balls (yo can consider them to be point charges) are in a test u tube, one vertically above the other as shown in the figure below. The balls are in equilibrium a distance d apart. If the charge on one of the balls is halved, the distance between the balls in the test tube would become A. 2d B. d/2 C. v2d D. d/v2 2....
