Velocity of efflux in torricelli's theor...


Velocity of efflux in torricelli's theorem is given by `v=sqrt(2gh)` here h is the height of hole from the top surface, after that motion of liquid can be treated as projectile motion.
Q. What is its time of fall of liquid on the ground?
(a). `(1)/(sqrt(2))s`
(b). `(1)/(sqrt(3))s`
(c). `(1)/(sqrt(5))s`
(d). `sqrt(2)s`

Text Solution

Verified by Experts

The correct Answer is:
C

`H=2sin30^(@)=1mthereforet=sqrt((2H)/(g))=(1)/(sqrt(5))s`
