Question

Cathode rays are passing through a discharge tube. In the tube, there is ______________ .

  • an electric field but no magnetic field

  • a magnetic field but no electric field

  • an electric as well as a magnetic field

  • neither an electric nor a magnetic field

Solution

an electric as well as a magnetic field

 

Cathode rays consist of beams of electrons that constitute current and, hence, magnetic field. We know electric field is produced by a charge, whether it is stationary or moving, So, electric field will also be present inside the tube.

  Is there an error in this question or solution?
