A: A large soap bubble expands while a small bubble shrinks, when they are connected to each other by a capillary tube
R: The excess pressure inside bubble (or drop) is inversely proportional to the radius

View answer and explanation

Correct option: C

A is true but R is false

Option C (A is true but R is false) is correct because while a larger bubble expands and a smaller bubble shrinks when connected, the excess pressure is inversely proportional to the radius, making the reason false.

The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
