Solution

The correct option is C water flowing through hole 'P' will move a smaller distance as compared to Q and R
Since the depth of point R is greater than that at P, the pressure at R is also greater.
From Bernoulli's equation, the velocity of water leaking out of the glass would also be greater at R than at P, though the height through which it would fall would be smaller.
Hence it cannot be ensured that water from P would move smaller distance as compared to others.

Question 2

Boojho and Paheli performed experiments taking similar bulbs and cells but two different solutions A and B as shown in Fig.

They found that the bulb in the setup A glows more brightly as compared to that of the setup B. You would conclude that
(a) Higher current is flowing through the circuit in setup A.
(b) Higher current is flowing through the circuit in setup B.
(c) Equal current is flowing through both the circuits.
(d) The current flowing through the circuits in the two setups cannot be compared in this manner.
