A 69.9-kg crate is suspended between the floor and the ceiling using two spring scales, one attached to the ceiling and one to the floor. If the lower scale reads 120 N, what is the reading of the upper scale?Ignore the weights of the scales.

hint: Are the forces balanced? Which are the forces acting downward?

Note:- I have used the correct method to solve the problem. The answer is not matching because , value of gravitational constant is not given and i have used as 9 = 9 . 81 m / s 2 . . If we use different value of 9 like 9 = 9 8 0 or 9= 10 m them answer will be different. # Salution : - Fup = Lg - Flower Caseus : - =D . Fup = (69 . 9 x 9 - 8 ) - 120 Fup = 565- 02 Newton Fup - 565 Newton Case (n) : - Fup = (69 . 9 x 10) - 120 Fup = 579 NewtonI conclusion :- The final answer is Case (is : - when 9 = 9 8 7 /5 2. Fup = 565.02 N = 565 N Caseup ! - when 9 = 9 :81 m / s 2 D Fup = 565- 72 N Case ( 11) ) : - when 9 = 10 m/s 2 Fup = 579 N Notel - if still not matching , please provide exact value of qn given in the question or a in the reference
