In a region of space, a uniform magnetic field B exists in the y-direction An electron is fired from the origin, with its initial velocity v making a small angle alpha with the y-direction in the yz plane. In the subsequent motion of the electron, a uniform magnetic field B exists in the y-direction An [...]

An electron and a proton each travel with equal speeds around circular orbits in the same uniform magnetic field as indicated (not to scale) in Fig. The field is into the page on the diagram. The electron travels ____ around the _____circle. A particle of charge q moves in a circle of radius r with [...]

Two particles Y and Z emitted by a radioactive source at P made tracks in a chamber as illustrated in the Fig. 1.134. A magnetic field acts downward into the paper. Careful measurements showed that both tracks were circular, the radius of Y track being half that of the Z track. Which one of the [...]
