Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The open-tube manometer
is the device that can be used to measure the pressure difference. It measures
the pressure of a gas is kept in its container. The pressure of the gas is
given by the height of mercury levels. Therefore it is a simple device that
compares the pressure within two containers.
Also, 1 unit of the bar
is equal to 105 Pascal.
But the reason for
working on this device is not based on the fact given as a unit of 1 Bar.
Thus assertion and
reason both are correct, but the reason is not appropriate.
Thus option B is
correct.
