Question

A stone is dropped into a well in which the level of
water is h below the top of the well. If vis velocity
of sound, the time after which the splash is heard
is given by
(A) T-2h/v
(B) T- 2.
01-
01-12​

Answer 1

Time taken for thw ball to reach the bottom  

= (2h/g)^1/2

Time taken by sound to reach the top  

= h/v  

Thus total time = (2h/g)^1/2 + h/v

Thus answer is B
