Three bodies P, Q and R have masses ' m ' kg , ' 2 ~m ' kg and ' 3 ~m ' kg respectively. If all the bodies have equal kinetic energy, then greater momentum will be for body/bodies.

Options

  1. AQ
  2. BR
  3. CP and Q
  4. DP

Correct answer

B. R

Step-by-step solution

Kinetic energy k = p ^2 2 ~m where p is the momentum p ^2=2 mk or p = 2 mk p m Hence body having greater mass will have greater momentum.
