Question
A string passing over a smooth pulley carries a stone at one end, while its other end is attached to a fixed end. A vibrating tuning fork is brought in contact with the stretched string and the string vibrates forming 8 loops. When the stone is completely immersed in water 10 loops are formed. The specific gravity of the stone is,
- 2.78
- 1.8
- 3.8
- 2.0
The correct answer is: 2.78
