Reading of both scales.
Answer to Problem 44A
One scale reads 400 N and other reads 800 N.
Explanation of Solution
Given:
Person H weight is 1200 N.
One bathroom scale reads twice the other.
Formula Used:
For mechanical equilibrium, summation of all forces is zero. That is
Calculation:
Weight of person H will be in downward direction.
Let one scale reads x N,
So, reading of other bathroom scale is 2x N.
Since, person H is in mechanical equilibrium so,
Upward force = Downward force
So, reading of first bathroom scale is 400 N and
Reading of other bathroom scale is
Conclusion:
Therefore, one scale reads 400 N and other reads 800 N.
