The figure shows crossed uniform electric and magnetic fields and, at a certain instant, the velocity vectors of the 10 charged particles listed in the table. (The vectors are not drawn to scale.) The speeds given in the table are either less than or greater than E/B (see Question 1). Which particles will move out of the page toward you after the instant shown in the figure? (Several choices may be correct.) 10 Particle Charge Speed Particle Charge Speed + Less Greater + Greater Less + Less + UAWNE Greater + Greater Less Less 10 Greater O Particle 1 O Particle 2 O Particle 3 O Particle 4 O Particle 5 O Particle 6 O Particle 7 O Particle 8 O Particle 9 O Particle 10A proton traveling at 33.3 with respect to the direction of a magnetic field of strength 2.95 mT experiences a magnetic force of 7.93 x 10-17 N. Calculate (a) the proton's speed and (b) its kinetic energy in electron-volts. (a) Number i Units (b) Number i UnitsIn the figure, an electron with an initial kinetic energy of 4.00 kev enters region 1 at time t = 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.00710 T. The electron goes through a half-circle and then exits region 1, headed toward region 2 across a gap of 22.0 cm. There is an electric potential difference AV = 2100 V across the gap, with a polarity such that the electron's speed increases uniformly as it traverses the gap. Region 2 contains a uniform magnetic field directed out of the page, with magnitude 0.0169 T. The electron goes through a half-circle and then leaves region 2. At what time t does it leave? B I Region 1 Region 2 OB2 Number UnitsIn a certain cyclotron a proton moves in a circle of radius 0.660 m. The magnitude of the magnetic field is 1.80 T. (a) What is the oscillator frequency? (b) What is the kinetic energy of the proton? (a) Number Units (b) Number i UnitsCurrent Attempt in Progress An electron moves in a circle of radius r = 6.74 X 10'11 m with a speed 3.37 X 106 m/s. Treat the circular path as a current loop with a constant current equal to the ratio of the electron's charge magnitude to the period of the motion. If the circle lies in a uniform magnetic eld of magnitude B = 7.5 1 mT, what is the maximum possible magnitude of the torque produced on the loop by the eld? Number n Units 4}
