Properties Of Solids And Liquids Question 268
Question: A silver ingot weighing 2.1 kg is held by a string so as to be completely immersed in a liquid of relative density 0.8. The relative density of silver is 10.5. The tension in the string in kg-wt is
Options:
A)1.6
B)1.94
C)3.1
D)5.25
Show Answer
Answer:
Correct Answer: B
Solution:
Apparent weight $ =V(\rho -\sigma )g=\frac{M}{\rho }(\rho -\sigma )g $
$ =M\left( 1-\frac{\sigma }{\rho } \right)g $
$ =2.1\left( 1-\frac{0.8}{10.5} \right)g=1.94g $ N= 1.94 Kg-wt
