Question

A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from the velocity selector at a speed of 2.82 ✕ 10⁵ m/s and enter a uniform magnetic field of 0.615 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by singly charged ions of ²³⁵U and ²³⁸U?

A solenoid 10.0 cm in diameter and 86.7 cm long is made from copper wire of diameter 0.100 cm, with very thin insulation. The wire is wound onto a cardboard tube in a single layer, with adjacent turns touching each other. What power must be delivered to the solenoid if it is to produce a field of 7.60 mT at its center? (Assume the resistivity of the copper wire is 1.70 ✕ 10⁻⁸ Ω · m.)
