Problem 8: Consider an experimental setup where charged particles (electrons or protons) are first accelerated by an electric field and then injected into a region of constant magnetic field with a field strength of 0.65 T.

What is the potential difference in volts required in the first part of the experiment to accelerate electrons to a speed of 6 1 × 107 m/s?

10581.59 V

Explanation:

We are given that

Magnetic field=B=0.65 T

Speed of electron=

Charge on electron,

Mass of electron,

We have to find the potential difference in volts required in the first part of the experiment to accelerate electrons.

Where V=Potential difference

Mass of electron

v=Velocity of electron

Using the formula

Hence, the potential difference=10581.59 V

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
