A 1.672*10^-27 kg proton is traveling at (3.0x10^6) m/s. How many Joules of kinetic energy does it have? Note: Your answer is assumed to be reduced to the highest power possible.

A positron (charge te, mass m) moves near a charge +3Q. The positron is moving with speed yo point A and moving at an angle so that it goes thru point B. What is the kinetic energy of the positron at point B? Assume that the charge +3Q is so massive that it does not move during this process. 3W OKEI=2 OKE= +3Q mu? O KE= OKE=2 mvå mua 2 mu!

The uniform electric field between two charged parallel plates has a magnitude of 4400 V/m (note that 1 V/m = 1 N/C). If the plates are separated by 0.0100 m and an electron is released from the far negative side of the gap, what will the electron's kinetic energy (in eV) and speed be when it just reaches the positive plate? Note that the electron charge = -1.602 x 10-19 C and the electron mass = 9.11 x 10-31 kg. KE V= ev m/s

2. In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The KE of the protons is used to kill cells in the tumor. For one patient, it is desired to deposit 0.1 J of proton energy into a tumor. To create the beam, proton at rest are accelerated through a potential difference of 10 MV (megavolts). a) What is the KE of a single proton fired at the tumor? b) How many protons must be fired at the tumor? ans. 6.25×1010 protons

Q8. Assume the electric potential at the negatively charged plate is zero. Clearly show all work! a) A charged particle A with charge + 0.020 C and mass 3.0x10-8 kg is at rest as shown next to the positive plate which has electric potential of 120 V. What is its kinetic energy when it reaches the negatively charged plate? What is its speed? b) Another charged particle B with charge + 0.060 C and mass 3.0x10-8 kg is at rest as shown. What is its kinetic energy when it reaches the negatively charged plate? What is its speed? c) A third charged particle C (not shown) with charge 0.070 C and mass 3.0x10-8 kg is at rest in the middle of the two parallel plates. How much work is needed to move it to the positively charged plate? Is the work positive or negative? 0 0 0 0 0 0 0 0

The distance, r, between the proton and electron in the hydrogen atom is about 1010 m. Determine the value of the kinetic energy of the electron. Provide your answer in electron-volts (eV).
