Question 56

A horizontal uniform calibration beam, $A B$ , has a length of 8.0 metres and is balanced on a narrow support at its center point $P$ . A precision weight of mass 9.45 kg is placed 1.6 metres to the left of $P$ . A second weight of mass 4.2 kg is placed $x$ metres to the right of $P$ so that the beam remains in a state of horizontal equilibrium.

Find $x$ .

Select your answer from the following choices:

$m3.2\text{ m}$

$m3.4\text{ m}$

$m3.6\text{ m}$

$m3.8\text{ m}$
