Question

An alpha particle has

Options

• Charge te

• A charge ze

• Charge to mass ratio equal to that of deuteron

• Mass equal to that of deuteron

Answer 1

Mass equal to that of deuteron

Explanation:

`("Charge"/"Mass")_alpha = (2e)/(4m) = 1/2 (e/m)_p`

`("Charge"/"Mass")` deutron = `1/2 e/m = 1/2 (e/m)_p`
