A.A wooden block of volume 1000 cm3 is suspended from a spring balance. Its weight is 12 N in air. It is suspended in water such that half of the block is below the surface of water. The reading of spring balance is : -
B.9 N
C.8 N
D.7 N
Solution
Reading of spring
= Mg - Th = Mg - Vlnρwg
= 12
103 × 10 = 7N
= Mg - Th = Mg - Vlnρwg
= 12
103 × 10 = 7NCreate a free account to view solution
