A) M
B) 2M
C) M/2
D) 4M
Correct Answer: B
Solution :
Mass of liquid in capillary tube \[M=\pi {{r}^{2}}H\times \rho \]\[\therefore \]\[M\propto {{R}^{2}}\times \left( \frac{1}{R} \right)\]\[(As\,H\propto 1/2)\] \[\therefore \]\[M\propto R.\] If radius becomes double, then mass will become twice.You need to login to perform this action.
