A stroboscopic photo of a club hitting a golf ball, such as the photo shown in the figure below, was made by Harold Edgerton in 1933. The ball was initially at rest, and the club was shown to be in contact with the ball for about 0.0020 s. Also, the ball was found to end up with a speed of 2.3 102 ft/s. Assuming that the golf ball had a mass of 55 g, find the average force exerted by the club on the ball.

Two large, parallel, conducting plates are 21cm apart and have charges of equal magnitude and opposite sign on their facing surfaces. An electrostatic force of 4.1 x10-15 N acts on an electron placed anywhere between the two plates.
Suppose a uniformly charged (with a linear charge density) wire starts at point 0 and rises vertically along the positive axis to a length. Determine the x-component of the electric field at point. That is, compute near one end of a long wire, in the..
