Water surface tension hold the needle on the water surface.
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
A needle can float on water due to surface tension. The water molecules at the surface stick together, creating a "film" strong enough to support the needle's weight without it sinking. This phenomenon is also why some small insects like water striders can walk on water.
A needle will sink in water because it is denser than water. The buoyancy force acting on the needle is not enough to counteract its weight, causing it to sink.
Surface tension of water is the property that allows a needle to float on water. This is due to the cohesive forces between water molecules at the surface, creating an invisible film strong enough to support the needle's weight without breaking.
A needle can be made to float on very still water.

Due to surface tension, the upper surface of water acts like a stretched membrane which enables it to float a swing needle.
Bouyancy is what makes a boat float
Surface tension
When a needle is placed on clean water, it can float due to surface tension, which is the cohesive force between water molecules at the surface. However, when detergent is added to the water, it reduces the surface tension by disrupting the cohesive forces between water molecules. This decrease in surface tension causes the needle to sink as the water can no longer support its weight.
A needle can float on water due to surface tension. The surface tension of water is strong enough to support the needle and prevent it from sinking, as long as the needle is carefully placed on the water and doesn't break the surface tension.
Yes if the surface tension of the water is not broken. If you are careful you can place a needle on the surface of the water in a glass. Also if you reduce the surface tension with detergent (just a very little is enough) the needle will sink because it's density is greater than that of the water. NO (if the surface tension of the water is broken, a needle cannot float on the surface of water. This is because the needle has higher density than water (density is mass divided by volume).
