Three bodies A, B and C have equal kinetic energies and their masses are 400 ~g . 1.2 ~kg and 1.6 ~kg respectively. The ratio of their linear momenta is :

Options

  1. A2 ; 3 ; 1
  2. B1: 3 : 2
  3. C1: 3 : 2
  4. D3 : 2 : 1

Correct answer

B. 1: 3 : 2

Step-by-step solution

aligned & KE = P ^2 2 ~m & P m aligned Hence, P _ A : P _ B : P _ C = 400 : 1200 : 1600 =1: 3 : 2
