7. Discuss the relative strengths of the Strong Force, the Electromagnetic Force, the Weak Force and the Gravitational Force.
Considering electron and proton as two charged particles separated by d = 5.9 × 10-11 m calculate the gravitational force between the proton and
electron and find its ratio to the Coulomb force. Take the mass of the proton 1.7 x 10-27 kg, the mass of the electron 9.1 x 10-31 kg, the value of
= 9x10⁹ m/F. Give the answer for
the universal gravitational constant 6.7 x 10-11 N kg 2m-2, the electron charge -1.6 x 10-¹9 C and
the gravitational force in 10-47 N.

For example, the Large Hadron Collider at CERN sends particles of opposite charges around a ring, with one beam traveling clockwise and the second traveling counterclockwise. Technically it is much more difficult to get the two beams to collide with one another in this way as compared to just having one beam slamming into a stationary target, yet this still how colliders are built. Consider the following two situations. In the first picture, (the modern collider design), two equal mass m particles collide, each with total energy Ecollider, to produce some exotic new particle of mass M, at rest. Conservation of energy says that 2Ecollider = Mc^2. On the other hand, in the second picture (the fixed-target design), a particle of mass m with energy Efixed hits an identical mass particle at rest, producing the same exotic new…arrow_forward

In the Bohr model for hydrogen, the radius of the nth orbit can be shown to be »² times the radius of the first Bohr orbit = 0.05 nm (see Example 10.3). Similarly, the energy of an electron in the nth orbit is times its energy when in the - 1 orbit. What is the circumference of the n = 100 orbit? (This is the distance the electron has traveled after having revolved around the proton once.) For such large-n states, the orbital frequency is about equal to the frequency of the photon emitted in a transition from the nth level to an adjacent level with n + 1 or n - 1. Given this, find the frequency and corresponding period of the electron's orbit by computing the frequency associated with the transition 100 to n = 101.

(The distance does not matter.) 2) There is an equilateral triangle with sides 2 meters in length.

(a) Viewers of Star Trek hear of an antimatter drive on the Starship Enterprise. One possibility for such a futuristic energy source is to store antimatter charged particles in a vacuum chamber, circulating in a magnetic field, and then extract them as needed. Antimatter annihilates with normal matter, producing pure energy. What strength magnetic field is needed to hold antiprotons, moving at 5.00 ×107 m/s in a circular path 2.00 m in radius? Antiprotons have the same mass as protons but the opposite (negative) charge.

Explain your reasoning. #9 The newly-formed nucleus would be much more stable if one of the protons could transform itself into a neutron. Fortunately, it can-and it does! One of the "up" quarks inside the proton turns into a "down" quark, releasing a positron and a neutrino in the process. What's left is a nucleus of hydrogen-2, also known as a deuteron.
