A: Needle placed carefully on the surface of water may float, where as a ball of same material sinks
R: Archimedes principle is applicable for only spherical bodies

View answer and explanation

Correct option: A

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

Option C is correct because a needle floats due to surface tension, while a ball sinks due to Archimedes' principle, and the reason incorrectly states Archimedes' principle only applies to spherical bodies.

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
