Assertion : Cathode rays get deflected towards the positive plate of the electric field. Reason : Cathode rays consist of negatively charged particles known as electrons.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Opposite charges attract each other. The cathode rays are negatively charged and therefore move towards the positive plate. So option (1) is correct.

The highest value of e/m of anode rays has been observed when the discharge tube is filled with
1 nitrogen
2 oxygen
3 hydrogen
4 helium
Explanation:
Hydrogen is the only element that does not carry any neutron. In anode ray discharge, it carries one positive charge and mass is also one. So, the e/m ratio is 1. But, for other gases as the molecular gas increases. The number of neutrons also increases so charge (number of proton) by mass (number of protons + number of neutrons) does not remain one but it becomes less than one because mass is always greater than charge except for hydrogen.

Which of the following statements is wrong about cathode rays?
1 They travel in straight line towards cathode.
2 They produce heating effect.
3 They are carrying negative charge.
4 They produce X - rays when strike with material having high atomic masses.
Explanation:
They travel in straight lines towards anode as they carry negative charge.

The study of cathode rays (i.e., electronic discharge through gases) shows that
1 \({\rm{\alpha - }}\) particles are heavier than protons
2 All forms of matter contain electrons
3 All nuclei contain protons
4 e/m is constant
Explanation:
J.J. Thomson determined the e/m value of the electron by studying the deflections of cathode rays in electric and magnetic fields. The value of e/m has been found to be \({\rm{ - 1}}{\rm{.7588 \times 1}}{{\rm{0}}^{\rm{8}}}\) C/g and always remains same.
