A solid weighs 10.00N in air, 6N when forcefully immersed in water, and 7.0N when fully immersed in a liquid, X. Calculate the relative density of the liquid X.
A
\(\frac{5}{3}\)
B
\(\frac{4}{3}\)
C
\(\frac{3}{4}\)
D
\(\frac{7}{10}\)
Verified Correct Answer: C.
Physical Principles & Numerical Solution
R.D = \(\frac{\text {weigh in air - weigh in liquid X}}{\text {weigh in air - weigh in water}}\)
= \(\frac{10 - 7}{10 - 6} = \frac{3}{4}\)
