Question

# An iron block and a wooden block are positioned in a vessel containing water as shown in the figure. The iron block (I) hangs from a massless string with a rigid support from the top while the wooden block floats being tied to the bottom through a massless string. If now the vessel starts accelerating upwards, the incorrect option is

- tension in the string 1 will increase
- tension in both the strings will increase
- tension in both the strings will decrease
- tension in the string 2 will increase

## The correct answer is: tension in both the strings will decrease
