A helium nucleus (mass = 6.64 × 10-27 kg, net charge = +2e)is fired directly toward a spherical conductor on a radiallyinward path. The conductor, which is fixed in place, has radiusR = 0.55 m and surface charge density o = +12 nC/m². If thehelium nucleus is initially very far away from the conductor, thenwhat initial speed must it be given so that it just barely avoidstouching the surface of the conductor before being repelled backto infinity? Make sure to draw a voltage vs. position curve forthe spherical conductor as part of your representation.

A sphere of uniform charge density rho=10^−6 C/m 3 has a small hole drilled along its diameter, forming a tunnel from one end of the sphere to the other. An electron is released at the opening of the tunnel and begins to move, speeding up towards the center of sphere. After it passes the center of the sphere, it begins to slow down until it reaches the other end of the tunnel and stops. The electron then moves back up to the first opening and start the cycle again. It repeats this cycle many times. Find the frequency of this cyclic motion.
Silicon wafers are made to create the most groundbreaking invention of mankind - microprocessors. If two silicon wafers (assume dipoles), both with masses of 125 grams, radii of 10 cm and thickness of 7x10^-6 m are placed close to each other, separated by a distance of 3 cm, what is the electric field strength experienced by an electron placed on the surface of the negatively charged wafer?

A particle with charge q = +1e and mass m = 8.5 × 10-26 kg is injected horizontally with speed 2.5 × 106 m/s into the region between two parallel horizontal plates. The plates are 28 cm long and an unknown distance d apart. The particle is injected midway between the top and bottom plates. The top plate is negatively charged and the bottom plate is positively charged, so that there is an upward-directed electric field between the plates, of magnitude E = 38 kN/C. Ignore the weight of the particle. When the particle exits the region between the plates, what will be the magnitude of its vertical displacement from its entry height, in millimeters?
