Question

Two 50 N weights are attached to a spring scale as as shown. What is the reading on the scale if the system is in equilibrium

• A. 100 N
• B. 0 N
• C. $5\sqrt{2N}$
• D. 50 N

Answer 1

The correct option is D 50 N

Given system is in equilibrium, hence tension in the string will be equal to the mass of the block.
$T=mg$
$T=50$ newton.
The spring scale measures the tension in the string.Hence it will show 50 newtons.
