@Kiran, 12.28÷60 = 0.2 not 2.

@ Deepak. You are close to the answer. Just covert the units. 125.28 is in rad/min. Divide by 60 to get 2 rad/sec.
12.28/60 ~ 2 rad/sec.
12.28/60 ~ 2 rad/sec.

Vessel height =( angula velocity^2 * radius^2)/2g.
(40) =(angular velocity ^2 * (sqrt(5)) ^2) /(2*9.81).
Angular velocity = 2rad/sec.
(40) =(angular velocity ^2 * (sqrt(5)) ^2) /(2*9.81).
Angular velocity = 2rad/sec.

Formula is.
Vessel height =( angula velocity"2 * radius"2)/2g.
Vessel height =( angula velocity"2 * radius"2)/2g.

(4/3 * r * h) * 3.14/180.
Putting the values;
4/3 * 40 * 2.23 * 3.14/180.
= 2.08 rad/sec.
Putting the values;
4/3 * 40 * 2.23 * 3.14/180.
= 2.08 rad/sec.

√ ((0.4*2*9.81)-0.05) = 2.79.
Hence answer is A correct.
Hence answer is A correct.
