Question

In the given figure mass of the blocks is 1 kg, what is the reading of the spring balance? (Take $g=10m/s^2$)

• A. 10 N
• B. 20 N
• C. 5 N
• D. Zero

Answer 1

The correct option is A 10 N

Reading will be equal to the tension in the string.

Since the system is in equilibrium, $T-mg=0$

So , $T=mg=10N$
