Two identical cans filled with water were taken and three holes were made on each of them at two different levels as shown in the figures.

Select the correct option regarding given can X and Y.

AForce of the water coming out from holes of can X is lesser than force of the water coming out from holes of can Y.
BJet coming from the can X travels further sideways as compared to jet from the can Y.
CPressure at all the three holes in can Y is same.
DBoth A and C


Ans 1:

Class : Class 5
This is a confusing question

Ans 2:

Class : Class 6
Ans is B and this answer is based on the Newton's 1st law:Law of Inertia. It tells that things wan Mt to continue to do what they were doing unless acted upon by an external force. So, jet of water from can X will go further sideways because the holes in can X are more far from the table than the holes in can Y.
