Question

1. Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 × 10-25 kg. The ions are accelerated from rest through a potential difference of 1.00 kV. Then, a 0.400 T magnetic field causes the ions to follow a circular path. Determine the radius of the path. Im 2. A rectangular current loop is located near a long, straight wire that carries a current of Iw 10 A (see the drawing). The current in the loop is 11-20 A. Determine the magnitude of the net magnetic force that acts on the loop. o11 n .15m 3. Two long, straight wires are separated by 0.12 m. The wires carry currents of 1.5 A in opposite directions, as the drawing indicates. Find the magnitude of the net magnetic field at the point A 0.060

Explanation / Answer

1) Solution-

the speed of ions

charge * potential = KE

3.20 x 10^-19 * 1000 = (1/2) * 3.27x10^-25 * v^2

v = 44240.10 m/s

Then... r = mv/qB = 3.27x10^-25 * 44240.10 / 3.20x10^-19*0.400 =

= 0.336 meters
