You wind a square coil 0.125 m on a side from a 5.00-m long piece of wire that has a mass of 0.190 kg. You then suspend the coil from one side (with a hinge arrangement) in a 0.0400 T magnetic field directed vertically upward by running a current of 3.70 A through the coil as shown. Hinged side (a) When the coil is in rotational equilibrium, determine the angle that the plane of the coil makes with the vertical. . with respect to the vertical (b) Determine the magnitude of the torque acting on the coil due to the magnetic force. IN . mAn ion that is doubly ionized passes through the velocity selector and into the deflection chamber of a mass spectrometer, as shown below. In the velocity selector the electric field has a magnitude of 7917 V/m, and the magnitude of the magnetic field in both the velocity selector and the deflection chamber is 0.0912 T. If in the deflection chamber the ion is detected at a distance of 39.6 cm from its entry point, determine the following. O B O . O + (@) mass-to-charge ratio of the ion kg/C b) mass of the ion kg (c) identity of the ion, assuming it's an element (Use only the masses of elements in their most common form as listed on the periodic table of elements.)A velocity selector in a mass spectrometer, like the one shown below, uses a 0.116 T magnetic field.
