Ratio of charge on positron to mass of positron is approximately

Options

  1. A+2 10¹¹
  2. B+5 10¹²
  3. C-2 10¹¹
  4. D-5 10¹¹

Correct answer

A. +2 10¹¹

Step-by-step solution

aligned & Charge on positron ( q )= e =1.6 10⁻¹⁹ C & Mass of positron ( m )= mass of electron & =9.1 10⁻³¹ ~kg & q m = 1.6 10⁻¹⁹ 9.1 10⁻³¹ =1.75 10¹¹ & 2 10¹¹ C / kg & aligned
