A) 0.4
B) 2.0
C) 0.1
D) 1.2
Correct Answer: B
Solution :
The linear speed of the liquid at the sides is \[r\omega \]. So, the difference in height is given as follows: \[2gh={{w}^{2}}{{r}^{2}}\] \[\Rightarrow \]\[h=\frac{{{(2\times 2\pi )}^{2}}{{(5\times {{10}^{-2}})}^{2}}}{2\times 10}\approx 0.02m\]You need to login to perform this action.
