The distance from the center of a seesaw where S should sit.
Answer to Problem 16PP
Explanation of Solution
Given:
Mass of A is
Mass of S is
Ashok sits at a distance of
Formula used:
The torque can be obtained by:
Where, F is the applied force, r is the distance of the point of application of force from the axis of rotation, and
Calculation:
When A and S sit on the seesaw, their weight will act in vertical downwards direction which generates torque.
The torque will be balanced about the pivot point that is the center of seesaw.
Let S sit at a distance
Substitute given values in above
Conclusion:
Thus, S should sit
