Question

A meter rod is supported at its middle point 0. The block of weight 10N is suspended at point B, 40cm from 0. Find the weight of the block that balance it at point A, 25 from 0​

Answer 1

Answer: oc Brown's school physics revision notes: GCSE physics, IGCSE physics, O level ... If a resultant force acts on an object about a fixed turning point (the pivot) it will ... You get situation B pedalling a bicycle when your foot and pedal are near the ... The weight of the block creates an anticlockwise moment (turning force) that ...

Answer 2

Answer:

Explanation:

The centre of gravity of a meter scale will be acting at the mid point (50 cm) of the scale.

For the balance, the moment of forces on both sides of knife edge will be equal.

So, mg×(55−50)=25g×(100−55) or m=225gram
