Question

Cathode rays are passing through a discharge tube. In the tube, there is (a) an electric field but no magnetic field

Answer 1

Yess then the cathode rays will move towards the positive electrode as when electric current is passed there we keep a cathode plate as perforated so when the rays passed through perforated cathode the +ion is coming out as they move towards the negative metal which is placed this shows that the particles are positive charge...
