A. 5.0 x 10-2 m-2.
B. 4.5 x 10-2 m-3.
C. 2.5 x 10-2 m8.
D. 2.0 x 10-2 m-3.
Correct Answer:
Option C = 2.5 x 10-2 m8.
Explanation
With in the air = 250N
wt. in the liquid = 200N
loss in wt. in the liquid = 250 – 200 = 50N
∴ Wt. the liquid of equal vol. of the iron = 50N
∴If the density of the liquid is 1000 lgm-3
then the volume of the liquid = (N)/D = V = (25kg)/1000 =0.025m3 = 2.5 x 10-2 m8.
