A spring balance reads when a ball of mass is suspended from it. A weighing machine reads when a beaker of liquid is kept on the pan of balance. When the ball is immersed in liquid, the spring balance reads and the weighing machine reads . The two balances are now so arranged that the suspended mass is inside the liquid in a beaker. Then,
View answer and explanation
Correct option: B
Option B () is correct because when the ball is immersed, it displaces liquid, increasing the weight measured by the weighing machine.
