Question

True or False, if false state why? a. The magnitude force if F_a is always perpendicular to the velocity v of the charged particles and to the magnetic field B. b. The earth's magnetic field is on the order of about 10.000 Gauss units. c. Faraday's the law say that the induced voltage in a circuit is proportional to the magnetic flux through the circuit. d. Two parallel wires carrying current in the same direction experience a repulsive force T or F. Three particles travels through a region of space where the magnetic field is out of the page, as shown in the figure. What are the signs of the charges these three particle? The magnetic field at a distance of 2 cm from a long straight current-carrying wire is 4 mu T. What is the magnetic field at a distance of 1 cm from this wire? A proton moving at 5.0 times 104 m/s horizontally enters a region where a magnetic field of 0.12 T is present, directed vertically downward. What magnitude force acts on the proton due to this field?

Explanation / Answer

5) a) True

magnetic force F = q(vxB)

b) True

c) False

from faradays law induced voltage is change in magnetic flux

d) False

6) 1)+ve chagre

2) nuetral

3) -ve charge

1) magnetic filed due to long current carrying wire B = uo*I/2pi*d

B1/B2 = d2/d1

4/B2 = 1/2

B2 = 8 uT

2) charge of proton m = 1.6*10^-19 C

v = 5*10^4 m/s, B = 0.12 T

F = qvBsin(90)

F = 1.6*10^-19*5*10^4*0.12*sin(90)

F = 9.6*10^-16 N
