Question

8. Charged particles are traveling in circular orbits with the speed v in a region of uniform magnetic field that is directed into the page, as shown What is the sign of cbarge q (Positive or xxx5 Negative?Q0Situ X x 9. Two particles of the same charge q enter a region of uniform magnetic field with the same speed, as shown below, that causes the beam to follow a semicircular path. The gyroradii are r and r2 for particle A and B, respectively. Since the force Fs on the particles due to the magnetic field is equal to the centripetal force Fc, radius of the circle can be found. (9a) Find the ratio of the mass between two particles, ?x x x x x x x xlxxxd x x x x x x x A B (9b) Which particle has bigger mass (Particle A or Particle B)?_ 10. A coil with 100 circular loops with radius 60cm carries a current of 5.0A. Find the distance x at which magnetic field dropped to 1/10th from the center.

Explanation / Answer

Answer: Positive

Explanation: Using the right hand rule, you can see that for the magnetic field is directed into the page...

   positive charges will move counter clockwise and negative charges will move clockwise. Here charge is moving counterclockwise so the charge should be positive in nature.
