A drum of radius R full of liquid of density d is rotated at 
. The increase in pressure at the outer edge of the drum will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
According to Bernoulli's Theorem
constant.
At sides the velocity is larger ( 
) so the pressure is lower. Since the pressure at a given horizontal level must be equal, the liquid rises at the sides to compensate for the drop of pressure.
