Chapter 2, Problem 44A

Harry Heavyweight, who weighs 1200 N, stands on a pair of bathroom scales so that one scale reads twice as much as the other. What are the scale readings?

Expert Solution & Answer
Check Mark
To determine

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

  F=0

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, F=0 or

Upward force = Downward force

  x+2x=12003x=1200Nx=400N

So, reading of first bathroom scale is 400 N and

Reading of other bathroom scale is 2x=2×400=800N

Conclusion:

Therefore, one scale reads 400 N and other reads 800 N.
