The $4.8\text{ kg}$, $5.0\text{ m}$-long beam in the diagram above is balanced horizontally on a pivot that is located $1.0\text{ m}$ from the left edge. Three objects with different densities are hanging from the beam. The left-most object has mass, $m_1=25\text{ kg}$ and is hanging $0.40\text{ m}$ from the left edge of the beam. The middle object has mass $m_2=1.0\text{ kg}$ and is hanging $2.0\text{ m}$ from the left edge of the beam. The right-most object hangs $4.4\text{ m}$ from the left edge of the beam.

Determine the mass, $m_3$, of the right-most object.

A

$m_3=2\text{ kg}$

B

$m_3=4\text{ kg}$

C

$m_3=9\text{ kg}$

D

$m_3=16\text{ kg}$

E

$m_3=19\text{ kg}$
