Text Solution

Verified by Experts

The correct Answer is:
A
The capaicty of the jar will be maximum if height and radius of the cyulinder are equal
`therefore` height = radius
Given diameter is k times the height of the jar
Diameter = 2 `xx` radius
`therefore` k=2

The first jar has a small hole on the side wall at a depth h//3 and the second jar has a small holw on the side wall at a depth of 2h//3 , where h is the height of the jar. The water issuing out from the first jar falls at a distance R_(1) from the base and the water issuing out from the second jar falls at a distance R_(2) From the base. The correct relation between R_(1) and R_(2) is
