1.Can a small child play with a fat child onthe see-saw?explain how.
2.Two children are sitting on the see-saw,such that they can not swing.What is the net torque in this situation?
3.Does the speed of a ceiling fan go on increasing all the time?
4.Does the ceiling fan satisfy second condition for equilibrium when rotating with uniform speed?
Yes. A small child can play with a fat child on a see saw, only if they both are at unequal distances from the pivot of the see saw. Such that the small child is farther from the pivot and the fat is closer. Then the see saw would be balanced and hence, they would be able to swing.
If two children are sitting on A see saw such that they cannot swing, then they will be satisfying the second condition of equilibrium, as the see saw has the tendency to rotate (until a limit.) Hence, the net torque will be zero (according to the second condition of equilibrium.)
Yee they can play on a see saw if they are sitting on unequal distance from the pivot
Yes a small child can play with a fat child on a seesaw ,only if both are at unequal distances from the pivot of seesaw such that a fat child should must be closer to the pivot of seesaw and small child should be farther then the seesaw would be balanced &hence they would be able to swing 💯💯
Yes,ofcourse a small child can play with a fat child on seesaw.
As we know that:
Sum of clockwise moments= Sum of anti-clockwise moments of equilibrium.
So,the distance from the pivot of the seasaw should be increased for the small child so that the moment of force or torque is increased.
Yes they can only if both are at unequal distances from pivot.
According to principle of moments sum of clockwise moments=sum of anticlockwise moments for a system or body to be balanced .the fat child has larger weight so he should be near to the pivot (there will be shorter moment arm ) whereas the small child should be further away from seasaw( there will be longer moment arm ). In this way system will be balanced and they can play sea saw . I hope this helps you:)
