Question

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, 36 N, 60 N, 44 N, 56 N

MARKS App · Accepted Answer

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
