Q.) In crossed field tubes, the electron beam traverses the length of the tube and is parallel to the electric field.

(A) true

(B) false

(D) ---

Correct answer : Option ( B) -

Explanation:

 in a crossed field or ‘m’ type tubes, the focusing field is perpendicular to the accelerating electric field. since the focusing field and accelerating fields are perpendicular to each other, they are called crossed field tubes.
