A long copper cylindrical shell of inner radius 2 cm and outer radius 3 cm surrounds concentrically a charged long aluminum rod of radius 1 cm with a charge density of 4 pC/m. All charges on the aluminum rod reside at its surface. The inner surface of the copper shell has exactly charge to that of the aluminum rod while the outer surface of the copper shell has the same charge as the aluminum rod. Find the magnitude and direction of the electric field at points that are at the following distances from the center of the aluminum rod: (a) 0.5 cm, (b) 1.5 cm, (c) 2.5 cm, (d) 3.5 cm, and (e) 7 cm.
From a distance of 10 cm, a proton is projected with a speed of v=4.0106 m/s directly at a large, positively charged plate whose charge density is =2.0105 C/m2. (See below.) (a) Does the proton reach the plate? (b) If not, how far from the plate does it turn around?

A +7.00 µC particle is located at x = 0.0 cm, and a –9.0 μC particle is located at x = 40.0 cm. Where must a positive test charge be placed along the x–axis so that the net electric force on it is zero? Hint: In a FBD, place the test charge left of x = 0 cm, in between the two source charges, and right of x = 40 cm. Sketch the direction and relative magnitude of the net force at each location and determine where it might be possible for the net force to be zero. Then set the magnitudes of the forces equal to each other.
Silicon wafers are made to create the most groundbreaking invention of mankind - microprocessors. If two silicon wafers (assume dipoles), both with masses of 125grams, radii of 10cm and thickness of 7 um are placed close to each other, separated by a distance of 3cm, what is the electric field strength experienced by an electron placed on the surface of the negatively charged wafer? What is the final velocity of the electron upon reaching the positively charged plate? How much power is generated by the electron in its travel?
In the figure below, a small, nonconducting ball of mass m = 1.4 mg and charge q = 2.2 ✕ 10−8 C (distributed uniformly through its volume) hangs from an insulating thread that makes an angle θ = 27° with a vertical, uniformly charged nonconducting sheet (shown in cross-section). Considering the gravitational force of the ball and assuming that the sheet extends far vertically and into and out of the page, calculate the surface charge density σ of the sheet. ___________C/m2
Imagine you have four identical charge q, placed on the corners of a square. If q = 4.69 nC, then the side of the square is s = 9.65 cm, calculate the magnitude of the electric field acting on the charge at the upper right corner. NOTE: Final answer in SIX decimal places. Then, state the SI unit of the variable being sought off.

For this physics II problem its saids a 4.00 g ping pong ball is suspended from a light thread and given an electric charge. The ball is then placed in a uniform electrci field of magnitude 110,00N/C which causes the ball to swing out to an angle of 23 degrees. What is the sign and magnitude of the charge on the ball? The ball is angled to the right. If you can break this down into step that would be great. Thanks!
