MCQ (Single Correct Answer)

-1

A particle of mass m₁ is moving with a velocity v₁ and another particle of mass m₂ is moving with a velocity v₂. Both of them have the same momentum but their different kinetic energies are E₁ and E₂ respectively. If m₁ > m₂ then :

E₁ < E₂

$${{{E_1}} \over {{E_2}}} = {{{m_1}} \over {{m_2}}}$$

E₁ > E₂

E₁ = E₂
