A cylindrical drum, open at the top, contains 30 litres of water. It drains out through a small opening at the bottom.10 litre of water comes out in time t, the next 10 litres in a further time t2 and the last 10 litres in a further time t3.Then
- a)t1 = t2 = t3
- b)t1> t2 > t3
- c)t1 < t2 < t3
- d)t2> t1 = t3
Correct answer is option 'C'. Can you explain this answer?

We know that,
Velocity of efflux is given as v = √2gh
As the water level in the tank decreases, the velocity with which water comes out from the opening decreases due to decrease in pressure with height. Hence, the time taken to empty the tank increases with decrease in velocity and height of water level.
Hence C is the correct answer.

Given information:
- A cylindrical drum contains 30 litres of water.
- Water drains out through a small opening at the bottom.
- 10 litres of water comes out in time t, the next 10 litres in a further time t2, and the last 10 litres in a further time t3.
To find: The relationship between t1, t2, and t3.
Solution:
Let's assume that the rate of water flowing out of the drum is constant, and it is equal to x litres per unit time. Then, we can use the formula:
Volume of water = Rate of flow x Time
Using this formula, we can calculate the time taken for each 10 litres of water to flow out of the drum.
- For the first 10 litres of water: Volume = 10 litres, Rate of flow = x, Time = t
- For the next 10 litres of water: Volume = 10 litres, Rate of flow = x, Time = t2
- For the last 10 litres of water: Volume = 10 litres, Rate of flow = x, Time = t3
We know that the total volume of water in the drum is 30 litres. So, we can write:
Volume of water = 30 litres = 10 litres + 10 litres + 10 litres
Using the formula, we get:
10 = x*t
10 = x*t2
10 = x*t3
Dividing the second equation by the first equation, we get:
t2/t = 1
Dividing the third equation by the first equation, we get:
t3/t = 1
Therefore, we can say that:
t2 = t
t3 = t
So, the relationship between t1, t2, and t3 is:
t1 = t
t2 = t
t3 = t
Hence, the correct answer is option 'C': t1 t2 t3.

We know that the total volume of water in the drum is 30 litres. So, we can write:
Volume of water = 30 litres = 10 litres + 10 litres + 10 litres

10 = x*t2
10 = x*t3

t2 = t
t3 = t
Hence, the correct answer is option 'C': t1 t2 t3.
