Question

# As shown in the figure, two equal masses each of 2 kg are suspended from a spring balance. The reading of the spring balance will be

- Zero
- 2 kg
- 4 kg
- Between zero and 2 kg

## The correct answer is: 2 kg

### In this case, one 2 kg wt on the left will act as the support for the spring balance. Hence its reading will be 2 kg
