Q.No.182: - Give three reasons to support the evidence that cathode rays are negatively charged electrons.

Q.No.182: - Give three reasons to support the evidence that cathode rays are negatively charged electrons.

Ans: - 1) When cathode rays are created then they move to the anode of the discharge tube which shows that they are negatively charges.

2) When an electric field is applied in the discharge tube then cathode rays experiences an attractive force toward the positive plate of the applied electric field which also shows that they have negative charge.

3) By applying the magnetic field these rays stats moving in a circle. By applying Right Hand Rule we concluded that they have negative charge.
