Question

The statements that is/are correct among the following is

• A. $e^{-}>H^{+}>H{e}^{2+}$ ( The order of charge/mass)
• B. Nature of cathode rays produced from He and H will be different
• C. Nature of canal rays produced from He and H will be different
• D. The charge by mass ratio of canal rays produced from H and He gases will be different.

Answer 1

Answer: (A), (C), (D)

The charge by mass ratio of canal rays produced from H and He gases will be different.

A) Smaller the charge, greater the charge/mass ratio.
B) Cathode rays are made up of electrons and hence their nature is independent of the gas used.
C) Canal rays are made up of positive charge species and is different for different gases. $H^{+}\text{and}H{e}^{+}$ will different charge by mass ratio.
D) Canal rays are made up of positive charge species and is different for different gases. $H^{+}\text{and}H{e}^{+}$ will have different charge by mass ratio.
