In Bohr's model for the Hydrogen atom, the electron when it is at the third level rotates in a circular orbit around the proton, at a radius of 4.7 x 10^-10 m. The proton has a positive electric charge of 1.6 x10^-19 C, while the electron has the same charge with an opposite sign. The electrical force between the two particles is responsible for the centripetal force that keeps the electron in its orbit. The mass of the proton is...

This is Problem 4.53 from John Taylor Classical Mechanics (a) Consider an electron (charge -e and mass m) in a circular orbit of radius r around a fixed proton (charge +e). Remembering that the inward Coulomb force ke²/r² is what gives the electron its centripetal acceleration, prove that the electron's KE is equal to -1/2 times its PE; that is, T = -1/2 U and hence E = 1/2 U. Now consider the following inelastic collision of an electron with...

1. You are being hunted by a raptor. It corners you, and begins to charge, qt a velocity of 20 m/s. You have constructed a trap. It consists of a trip wire that will knock the raptor down and transfer all of its KE to a phaser rifle that requires 80 kJ of energy to fire directly at your foe. If the raptor has a mass of 150 kg, will the rifle gain enough energy to fire? a)no b)not enough...

2. In 1993 the Galileo spacecraft sent home an image of asteroid “243 Ida” and a tiny moon “Dactyl” orbiting the asteroid. Assume that the small moon orbits in a circle with a radius of r = 100 km from the center of the asteroid with an orbital period of T = 27 hours. a) Show and explain how we derived Kepler’s 3rd law in class using Newton’s 2nd Law, the definition for centripetal acceleration, and the equation for the...

1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...

MOMENT OF INERTIA LAB Apparatus Only (P3) With Masses (P4) With Block (P5) Setup You have a T-shaped apparatus that can spin about a vertical axis. One end of a light string is wrapped around the vertical shaft of the apparatus. The other end passes over a pulley and has a known mass hung from it to establish tension in the string. By measuring the acceleration of the hanging mass, the rotational inertia of the apparatus can be determined. Specifically,...
