Fluid Mechanics Viscosity Question 257
Question: A hollow sphere of mass $ M=50kg $ and radius$ r={{\left( \frac{3}{40\pi } \right)}^{1/3}} $ m is immersed in a tank of water (density $ {\rho_{w}}=10^{3}kg/m^{3} $ ). The sphere is tied to the bottom of a tank by two wires A and B as shown. Tension in wire A is$ (g=10m/s^{2}) $
Options:
A) $ 125\sqrt{2}N $
B) $ 125N $
C) $ 250\sqrt{2}N $
D) $ 250N $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ T_{1}={T_{2,}},Mg+\sqrt{2}T_{1} $ $ =\frac{4}{3}\pi r^{3}{\rho_{w}}g,,T_{1} $ $ =250\sqrt{2}N $
