Question

1) The Earth's magnetic field is 0.1 millitesla and at 66 degrees from the horizontal. The magnetic field for the apparatus in the experiment is 1.3 millitesla. How much difficulty will the Earth's magnetic field cause in the experiment?

2) If it were possible to arbitrarily orient the apparatus (below), in what direction (parallel, anti-parallel, perpendicular, or other) should it be aligned in order to minimize the effects of the Earth's magnetic field? Why?

I would really appreciate any help!

The Earth's magnetic field is 0.1 millitesla and at 66 degrees from the horizontal. The magnetic field for the apparatus in the experiment is 1.3 millitesla. How much difficulty will the Earth's magnetic field cause in the experiment? If it were possible to arbitrarily orient the apparatus (below), in what direction (parallel, anti-parallel, perpendicular, or other) should it be aligned in order to minimize the effects of the Earth's magnetic field? Why? Cathode, Grid and Anode. The electrons are accelerated down from the cathode to the anode. Their initial direction is down and their path of motion will be bent to the left in the above diagram by the magnetic field

Explanation / Answer

1. if apparatus is unsheilded , there may be an error upto = 1.3/(1.3-0.1) = 1.3/1.2 = 1.0833

error may be to 8.333%

b. it jmsut be aligned pperpendicualr to the filed
