A particle of mass 5.7 x 10 kg and charge +8.9 µC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 4.1 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number Units

A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.

A beryllium-9 ion has a positive charge that is double the charge of a proton, and a mass of 1.50 ✕ 10−26 kg. At a particular instant, it is moving with a speed of 5.10 ✕ 106 m/s through a magnetic field.

Problem 4 = The figure below shows a mass spectrometer, a device used to measure the masses of ions. Consider a positive ion of unknown mass m and charge q 4.8 x 10-19 C. The ion is first accelerated from rest through a potential difference AV inside a source. After leaving the source, it travels rightward at constant speed and enters a region of uniform magnetic field B 3.5 T directed out of the page. The ion then moves in a semicircle of radius r within the field, striking a plate at a vertical distance x = 12 m below its point of entry. Ignore the effect of gravity.
