Part III: The Inner Workings of the SunNow let's consider the effect that each of the four fundamental forces has on the inner workingsof our Sun:#6 The Sun produces energy by fusing hydrogen nuclei (protons) together to make helium.But protons are positively charged, so as they approach each other they initially feel astrong repulsive force. Which fundamental force would this be? Explain your reasoning.#7 In order for fusion to occur, protons must be moving very fast so they can get very closetogether before the repulsive force of Question #3 can separate them. Fortunately, thevery high pressure and temperature in the core of the Sun are exactly what's needed toget them moving that quickly. Which of the four fundamental forces compresses thecores of very massive objects like the Sun? Explain your reasoning.

Coulomb’s law tells us that the electrostatic force between two charged objects can be calculated by: ?= ??1?2/?^2Where k is a constant with a value of 8.99x109 Nm2/C2; ?1 and ?2 are the charges of the two particles (1.602x10-19 C), and r is the distance between the two particles. The force is attractive if the charges of the two particles is opposite (one’s positive and one’s negative) and repulsive if the charges have the same charge (both positive or both negative). Calculate the electrostatic force on proton #1 from the other two protons.Will the gravitational force between the protons be attractive or repulsive? What about the electrostatic force? Which has the larger magnitude, the electrostatic force or the gravitational force? Can the electrostatic and gravitational forces alone create a stable Lithium nucleus?

3. Each small sphere shown has a charge of magnitude q but the stationary charge in the center is negative while the two moving charges are positive. The moving charges (each of mass 0.20 kg) are attached to the ends of 4.0 m long strings and they are moving like conical pendulums as shown at a constant velocity of 12.0 m/s in uniform circular motion. The strings each make an angle of 30° to the vertical. Find the magnitude of the charge q. 300: 30° 4.0 m 4.0 m + q - 9 +q
3) Skid Infinite Black Pit Mitch Skid of 40 kg and Mitch of 60 kg are standing on ice on opposite sides of an infinite black pit. They are each carrying neutral massless spheres while standing 8 m apart. Suppose that 3.0 x 10¹5 electrons are removed from one sphere and placed on the other. (a) Calculate the magnitude of the electrostatic force on each sphere. Are the forces the same or different? Explain. (b) Calculate the magnitude of the accelerations for Skid and Mitch at the moment they are 8 m apart. Are they the same or different? Explain. (c) As Skid and Mitch move closer together do their accelerations increase, decrease, or remain the same? Explain.

3 Charge Deflector E beam An experiment to look for a charge imbalance between the proton and electron is constructed as shown. A beam of particles moving at speed vo = 1.0 x 106 m/s is prepared in an accelerator. Before striking the detector, the beam passes through a region of length L = 10 m that contains a uniform electric field of strength & = 100 N/C perpendicular to the beam. (a) Where would a proton from the beam be expected to strike the detector? (L.e., how many meters above or below the beam line would it strike?) (b) Where would an electron from the beam be expected to strike the detector? (L.e., how many meters above or below the beam line would it strike?) (c) We do not believe a hydrogen atom has any charge, but an experiment can only put an upper limit on the net charge - not prove that it is zero. Suppose the detector in this experiment is unable to detect a deflection less than 1 nm. I.c., if the deflection is 1 nm or less, the detector will register "0" deflection.…
5.) Protons can be approximated as spheres with a radius of about 8.5 x 10-16 m. Using Coulomb's law (which we saw at the beginning of the year), calculate the force required for two particles with the charge of one proton to be this far apart. While not exact, this gives a sense for how much force must be applied for the first step of this process to occur. Note: you will have to look up a couple of values here .. units are important, so it's probably best to work in Sl units.
