Question

deepta and abhinav having weight 450N and 350N are playing seesaw. If deepta sits at a distance of 2cm from fulcrum, how far should abhinav be seated in order to balance feel ya?​

Answer 1

The distance Abhinav should be seated from the fulcrum in order to balance the seesaw is 2.57 cm

Step-by-step explanation:

For mechanical advantage of a seesaw, we have

Work done by Deepta = Work done by Abhinav

Weight of Deepta × Distance of Deepta from fulcrum = Weight of Abhinav × Distance of Abhinav from fulcrum

The given information are;

The weight of Deepta = 450 N

The weight of Abhinav = 350 N

The distance of Deepta from the fulcrum = 2 cm = 0.02 m

The distance of Abhinav from the fulcrum = X

Which gives;

450 × 0.02 = 350 × X

X = 450 × 0.02/350 = 0.0257 m = 2.57 cm

Therefore, Abhinav should be seated at 2.57 cm from the fulcrum in order to balance the seesaw.
