Two particles A and B having same mass have charge +q and +4 q respectively. When they are allowed to fall from rest through same electric potential difference, of ratio of their speeds ' V_A ' to ' V_B ' will become

Options

  1. A1:2
  2. B2:1
  3. C1:4
  4. D4:1

Correct answer

A. 1:2

Step-by-step solution

If V is the potential difference then aligned & 1 2 ~m v_ A ^2= qV & and 1 2 ~m v_ B ^2=4 qV & v_ A ^2 v_ B ^2 = 1 4 & v_ A v_ B = 1 2 aligned
