Question

Determine the charge to mass ratio of beta negatives

Answer 1

Answer:

Let us consider

Charge of proton = +e

Mass of proton = m

Charge of helium = +2e

Mass of helium = 4m.

Specific charge (e/m) value of proton = e/m

Specific charge (e/m) value of helium = 2e/4m

The ratio of these two given as follows

(e/m) × (4m/2e) = 2:1

Therefore, the charge to mass ratio of an alpha particle is approximate twice the charge to mass ratio of a proton
