A body is suspended by a light string. The tensions in the string when the body is in air, when the body is totally immersed in water and when the body is totally immersed in a liquid are respectively \(40.2 \mathrm{~N}\), \(28.4 \mathrm{~N}\) and \(16.6 \mathrm{~N}\). The density of the liquid is
- A \(1200 \mathrm{~kg} \mathrm{- \textrm {m } ^ { - 3 }}\)
- B \(1600 \mathrm{~kg}-\mathrm{m}^{-3}\)
- C \(2000 \mathrm{~kg}-\mathrm{m}^{-3}\)
- D \(2400 \mathrm{~kg}-\mathrm{m}^{-3}\)
Answer & Solution
Correct Answer
(C) \(2000 \mathrm{~kg}-\mathrm{m}^{-3}\)
Step-by-step Solution
Detailed explanation
Density of water-Density of air \(\propto T_{\text {water }}-T_{\text {air }}\) Density of liquid-Density of water \(\propto T_{\text {liquid }}-T_{\text {water }}\) Now, from given values, \(T_{\text {water }}-T_{\text {air }}=T_{\text {liquid }}-T_{\text {water }}\) Air…
