The correct Answer is:
To solve the question, we need to evaluate the two statements given and determine their correctness and relationship. ### Step 1: Analyze Statement-1 **Statement-1**: A thin stainless steel needle can lay floating on a still water surface. - A thin stainless steel needle can indeed float on water due to the phenomenon of surface tension. The surface tension of water creates a force that can support the weight of the needle, allowing it to float even though the needle is denser than water. ### Step 2: Analyze Statement-2 **Statement-2**: Any object floats when the buoyancy force balances the weight of the object. - This statement is a fundamental principle of buoyancy. According to Archimedes' principle, an object will float if the buoyant force acting on it (which is equal to the weight of the fluid displaced by the object) is equal to the weight of the object. If the buoyant force is greater than the weight, the object will rise, and if it is less, the object will sink. ### Step 3: Determine the Relationship between the Statements - While both statements are correct, they refer to different physical principles. Statement-1 is about the floating of the needle due to surface tension, while Statement-2 refers to the general principle of buoyancy. ### Conclusion - Both statements are correct, but Statement-1 is not explained by Statement-2. Therefore, the correct answer is that both statements are true, but Statement-2 does not correctly explain Statement-1. ### Final Answer - Statement 1 is correct, Statement 2 is correct, but Statement 2 does not explain Statement 1. Hence, the answer is option B. ---

Statement-1:Alkanes float on the surface of water Statement-2: Density of alkanes is in the range of 0.6-0.9 g/ml , which is lower than water.

A needle can float on clear water but sinks when some detergent is added to it. This happens because

Statement - 1 : When hot water is poured in a beaker of thick glass, the beaker cracks. Statement - 2 : Glass is a bad conductor of heat and outer surface of the beaker does not expand.

Statement I: A needle placed carefully on the surface of water may float, whereas the ball of the same material will always sink. Statement II: The buoyancy of an object depends both on the material and shape of the object.

Statement-1 : When two soap bubbles of unequal radii are connected by a tube, the smaller bubble decreases in size. Statement-2 : In floating, weight of the floating body is equal to the weight of displaced fluid. Statement-3 : When ice converts into water its volume decreases.

A ball floats on the surface of water in a container exposed to atmosphere. Statement-1 : If the container is shifted to moon, the ball will rise a little (gravity on moon is (1)/(6) th that on the earth). And Statement-2 : Buoyant force on the ball will decrease.

Assertion : A solid object of iron is dipped in water, both are at same temperature of 2^(@)C . If the temperature of water is increased by 2^(@)C , then the buoyancy force action of the object will increase. Reason : If we increase the temperature of water from 2^(@)C " to " 4^(@)C , then density of water will increase. Ignore expansion of solid sphere.
