Question

which of the following species has maximum charge to mass ratio​
D+
H+
He+
He2+

Answer 1

Answer:

H+

Explanation:

e / m ratio is the charge by mass ratio of the electron.

By determination of the energy of electrons and their total magnetic field strength, the ratio of the charge to mass (e/m) of the electron is thus determined.

For D+ charge is one and the mass is also two, thus ratio is 0.5.

For H+ charge is one and the mass is also one, thus ratio is 1.

For He2+, charge is two and mass is four, thus ratio will be 0.5.

For He+, charge is one and mass is four,thus ratio will be 0.25

Therefore, the maximum charge to mass ratio​ is of H+.

Answer 2

Answer:

Explanation:

e / m ratio is the charge by mass ratio of the electron.

By determination of the energy of electrons and their total magnetic field strength, the ratio of the charge to mass (e/m) of the electron is thus determined.

For D+ charge is one and the mass is also two, thus ratio is 0.5.

For H+ charge is one and the mass is also one, thus ratio is 1.

For He2+, charge is two and mass is four, thus ratio will be 0.5.

For He+, charge is one and mass is four,thus ratio will be 0.25

Therefore, the maximum charge to mass ratio​ is of H+.
