The specific charge of a proton is 9.6 10^7 C / kg . The specific charge of an alpha particle will be

Options

  1. A9.6 10^7 C / kg
  2. B19.2 10^7 C / kg
  3. C4.8 10^7 C / kg
  4. D2.4 10^7 C / kg

Correct answer

C. 4.8 10^7 C / kg

Step-by-step solution

Specific charge on proton = ( e m )_p=9.6 10^7 C / kg Specific charge on -particle, ( q m )_ = 2 e 4 m = 1 2 ( e m )_p= 1 2 9.6 10^7=4.8 10^7 C / kg
