MCQ
X-ray beam can be deflected:
  • A
    By an electric field.
  • B
    By a magnetic field.
  • C
    By an electric field as well aa by a magnetic field.
  • D
    Neither by an electric field nor by a magnetic field.

Answer

  1. Neither by an electric field nor by a magnetic field.

Explanation:

Since X-rays do not have any charged particles, they are not deflected by an electric field or a magnetic field.
