1.31P Centre of gravity question 1
Diagram 1 shows a wooden plank balanced horizontally on two supports, A and B.
A block is suspended from the plank between the supports by a cable of negligible weight.
Diagram 1
Diagram 2 shows the block and the cable connecting the block to the plank.
The centre of gravity of the block is located at point X .
Draw an arrow on diagram 2 to show the weight of the block.
