Question

An ideal liquid having total length of liquid column L is contained in V-shaped tube as
shown. The system is in lift which is moving in upward direction with constant
acceleration a. If liquid is displaced, then its time period is​

Answer 1

Answer:

g effective = g+a

Then

Time Period = 2π√l/g+a

Answer 2

Given :

Length of liquid column= L

Acceleration of lift = a

To find :

Time period = ?

Solution :

• The resultant acceleration of the liquid column would be g+a as it is moving in upward direction

• Time period (T) = 2π ×√(l/g)

• By substistuting the value of resultant acceleration

       T = 2π ×√(l/g+a)

The time period is T = 2π ×√(l/g+a)
