Question

The inside edge of the visible electron beam appears fuzzy. Which one of the following statements is the best explanation of this?

a) Electrons that have undergone a collision have lost some of their speed and therefore the radius of their trajectory is larger.

b) Electrons that have undergone a collision have lost some of their mass and therefore the radius of their trajectory is larger.

c) Electrons that have undergone a collision have lost some of their mass and therefore the radius of their trajectory is smaller.

d) Electrons that have undergone a collision have gained some energy and therefore the radius of their trajectory is smaller.

e) Electrons that have undergone a collision have lost some of their speed and therefore the radius of their trajectory is smaller.

f) Electrons that have undergone a collision have gained some energy and therefore the radius of their trajectory is larger.

The electrons which enter into collsiions lose some energy. so, the inside of the electron beam is fuzzy.

Therefore,Electrons that have undergone a collision have lost some of their speed and therefore the radius of their trajectory is smaller

option (e) is correct answer.
