A $20 N$ metal block is suspended by a spring balance. A beaker containing some water is placed on a weighing machine which reads $40 N$ . The spring balance is now lowered so that the block gets immersed in the water. The spring balance now reads $16 N$ . The reading of the weighing machine will be

Options:

Answer:

Solution:

Let Reading of spring balance $= R_{1}$

And reading of weighing machine be $= R_{2}$

$∴$ $R_{1} + R_{2} = w_{1} + w_{2}$

$16 + R_{2} = 20 + 40$

$R_{2} = 44 N$
