1. Two parallel current carrying wires will attract each other if: (a) Current run through the wires in opposite directions. (b) Current run through the wires in the same direction. (c) The wires cannot attract each other. 2. How could the force exerted on a straight wire that carries current due to Earth’s magnetic field be minimized? (a) Align the...

Beams of high-speed protons can be produced in "guns" using electric fields to accelerate the protons. Find the acceleration would a proton experience if the gun's electric field were 2.72 × 104 N/C. What speed would the proton attain if the field accelerated the proton through a distance of 1.17 cm? (enter speed for answer).

A strip of invisible tape
0.13 m long by 0.011 m wide is charged uniformly with a total net
charge of 4 nC (nano = 1 ✕ 10−9) and is suspended horizontally, so
it lies along the x axis, with its center at the origin, as shown
in the figure below. Calculate the approximate electric field at
location 0, 0.02,...

October 21, 2015 has past and the Cubs did not win the World Series nor did you get your hoverboard. Clearly, the "flux capacitor" is not working.1 Based on visual inspection, the flux capacitor operates by combining three streams of high magnetic field At a central point. If each stream has a magnetic field of 1.21 T and the intercepting...

fe ln he C charge in the y- and x- cdirections Problem 3 Separating Charges In the previous homework, we considered an alpha particle being accelerated towards a gold nucleus. One way to "create" alpha particles is by placing neutral Helium into a uniform, constant electric field and "tearing" (accelerating) the electrons away from the nucleus. What is the minimum...
