A charged particle with a charge-to-mass ratio of lql/m = 5.7 x 108 C/kg travels on a circular path that is perpendicular to a magnetic field whose magnitude is 0.65 T. How much time does it take for the particle to complete one revolution? t = i

A magnetic field has a magnitude of 0.0014 T, and an electric field has a magnitude of 3.5 × 103 N/C. Both fields point in the same direction. A positive 1.7-μC charge moves at a speed of 2.8 x 106 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge.

In a mass spectrometer, a doubly charged ion having a particular velocity is selected by using a magnetic filed of 130 mT perpendicular to an electric field of 6.9 kV/m. The same magnetic field is used to deflect the ion in a circular path with a radius of 93 mm. What is the mass of the ion? The mass, m = Incorrect Units           Correct .

Problem 5: An electron (q= -e = -1.60 × 10-19 C and me = 9.11 × 10-31 kg) in a cathode-ray tube is accelerated through a potential difference of 10 kV. Thus, the electron leaves the cathode-ray tube with a speed v = 5.93 × 107 m/sec. The electron then passes through the 2.0 cm wide region of uniform magnetic field (shown in the Figure above on the right). What field strength will deflect the electron by 10°? Answer: B = 0.0029 T. OV 10 kV 2.0 cm 10°
