Q117 / 150 · MHT CET 2024 (09 May Shift 2) · Physics

The van de Graaff Generator is not based on

A
the phenomenon of Corona Discharge in X-ray tube.
Correct answer
B
the application of electric field and magnetic field which are perpendicular to each other.
C
the property that charge given to a hollow conductor is transferred to its outer surface and distributed uniformly over it.
D
the fact that a charge is continuously supplied to an isolated metallic conductor, the potential of the conductor goes on increasing.

Solution

This option refers more to the principles behind devices like a cyclotron, not the Van de Graaff generator. The Van de Graaff generator does not rely on magnetic fields and electric fields being perpendicular.

Hence, the correct answer is option: 'B'.
