NDA 2023 Physics question
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume () submerged. On the other hand, on a spaceship accelerating with acceleration ( is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is . Then :
Answer: (A)
Solution
For a floating body, weight = buoyant force: , so . The effective
