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

Assertion: A needle placed carefully on the surface of the water may float, whereas a ball of the same material will always sink. Reason: The buoyancy of an object depends both on the material and shape of the object Correct Answer Assertion is true but the reason is false

The assertion is true but the reason is false. The needle floats because the force of surface tension on it is enough to balance its weight. In the case of the ball, the resultant of the force of surface tension and buoyancy is enough to balance the weight of the ball.
