✓
Magnetic poles
C
Equator
D

A particle of mass $m_1$ is moving with a velocity $v_1$ and another particle of mass $m_2$ is moving with a velocity $v_2$. Both of them have the same momentum but their different kinetic energies are $E_1$ and $E_2$ respectively. If $m_1>m_2$ then

$E_1 < E_2$
$\frac{E_1}{E_2}=\frac{m_1}{m_2}$
