A: A hydrogen filled balloon stops raising after it has attained a certain height in the sky
R: The buoyancy of an object depends both on the material and shape of the object

View answer and explanation

Correct option: A

Both A and R are true and R is the correct explanation of A

Option A is correct because a hydrogen balloon stops rising due to buoyancy changes with altitude, and the reason correctly explains this dependence on material and shape.

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. 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
