Refer to the figure above, in which $m_1$ and $m_2$ are connected via a light cord which passes over a massless pulley. Take $m_2 > m_1$, such that $m_2$ remains on the floor while $m_1$ remains suspended.

What is the normal force $F_N$ exerted on $m_2$?

A

$m_1 g$

B

$m_2 g$

C

$(m_2 - m_1) g$

D

$(m_2 + m_1 ) g$

E

$\frac {m_2 - m_1} {m_2 + m_1} m_2 g$
