Question

e/m value for positive is minimum for ?

Answer 1

Explanation:

E/m value of positive rays is maximum for : a) Hydrogen b) Helium c) oxygen d) Nitrogen

Answer 2

Answer:

The highest value of e/m of anode rays has been observed when the discharge tube is filled with hydrogen. Anode rays consists of positively charged ions obtained by removal of one or more electrons from neutral gaseous atom. Among the given gases, hydrogen has least mass. Hence, it has maximum value of e/m.
