A bomb at rest explodes into 3 parts of same mass. The momentum of two parts is - 3 p i ^ and 2 p j ^ respectivley. The magnitude of momentum of the third part is

Options

  1. Ap
  2. B5 p
  3. C11 p
  4. D13 p

Correct answer

D. 13 p

Step-by-step solution

As initial momentum is zero, final will be also zero ∴ p 3 = 9 p 2 + 4 p 2 = 13 p .
