Experiments indicate that 13.6 eV are needed to separate the electron from the proton in the hydrogen atom. Compute the velocity of the electron assuming that hydrogen is described by the Rutherford-Bohr model and the electron occupies an orbit with the Bohr radius.
A proton travels with the speed of 8.34×105 m/s at an angle of 32.3° with the direction of a magnetic field. The field exerts a force of 3.00×10-17 N on the proton. What is the strength of the field.
Two polarizers are aligned to the angle between their polarization direction is 45 degrees. what fraction of the incident intensity is transmitted though the second
During the collision with the ground, he comes to rest in a time of .101 s. The average force exerted on him by the ground is +18000 N, where the upward direction is taken to be the positive direction. Elucidate from what height did the student f..
