The specific charge of a proton is 9.6×10⁷ C/kg. The specific charge of an alpha particle will be

Options

(a) 9.6 x 10⁷ C kg⁻¹
(b) 19.2 x 10⁷ C kg⁻¹
(c) 4.8 x 10⁷ C kg⁻¹
(d) 2.4 x 10⁷ C kg⁻¹

Correct Answer:

4.8 x 10⁷ C kg⁻¹

Explanation:

For proton, specific charge = e / m = 9.6 × 10⁷ C kg⁻¹

For alpha particle, specific charge = 2e / 4m = 1e / 2m

= (1/2) × 9.6 × 10⁷ = 4.8 × 10⁷ C kg⁻¹
