In which condition can an object float on water?

A. object की average density water से कम हो / Its average density is less than water

Step 1: Identify the concept: this is floating and density. Step 2: If average density of object is less than water buoyant force can balance weight and object floats. Step 3: Remember low density helps floating.

Step 1: concept पहचानें: यह floating और density है। Step 2: अगर object की average density water से कम हो तो buoyant force weight को balance कर सकता है और object float करता है। Step 3: Low density helps floating याद रखें।
