(3) Two protons are initially both traveling with velocity i= -1.91 x 10°m/sj while sepa- rated by a distance of 54.8 fm. While these protons interact, they will begin to move away from one another and end up infinitely far away from one another. (a) Draw a picture of the protons in their initial state. Label the separation and the velocity on the image. Be sure to include a labeled set of axes. (b) What is the closest separation between these protons during their motion? (c) When the protons are infinitely far apart, one will have a speed which is 4.53 times larger than the other proton. What are the final velocities of these protons?

The distance, r , between the proton and electron in the hydrogen atom is about 10-10 m. Determine the value of the kinetic energy of the electron. Provide your answer in electron- volts (eV). Answer: Choose... +

In an oil-drop experiment similar to Millikan’s, an oil droplet is suspended between two parallel, charged plates. Calculate the magnitude of the charge on the oil droplet if the radius of the oil drop is 4.2 x 10^-6 m, the density of the oil is 7.8 x 10^-2 g/m^3, the distance between the plates is 2.0 cm, and the potential difference between the plates is 99 V.

For problem 49 of the text, calculate the initial speed of the third electron in m/s using a separation of the other two electrons of 0.66 m. Answer in 5 sig figs!!!

We will do the following processes:a) First we take three point particles of mass (m1, m2, m3) from infinity and glue them to positions (x1, x2, x3) relative to some global inertial reference system.b) We now carry three positively charged particles qi, i ∈ (1, 2, 3) from infinity and glue them to positions (y1, y2, y3) relative to some global inertial reference system.Explain of these two processes if the external world gained or lost energy?Evaluate the energy gained or lost from the outside world. Is there conservation of energy in these processes?
