If a solid X floats in liquids P of relative density 2.0 and in liquid Q of relative density 1.5, it can be inferred that the
- A. weight of P displaced is greater than that of Q
- B. weight of P displaced is less than that of Q
- C. volume of P displaced is greater than that of Q
- D. volume of P displaced is less than that of Q
Correct Answer: A. weight of P displaced is greater than that of Q
Explanation
R.d \(\alpha\) weight of liquid displaced
\(\frac{\text {R.d of P}}{\text {R.d of Q}}\) = \(\frac{\text{weight of p displaced}}{\text{weight of Q displaced}}\)
\(\frac{2}{1.5}\) = \(\frac{\text {weight of p displaced}}{\text {weight of Q displaced}}\)
