A solid body will float in a liquid if its
density is less than that of a liquid
mass is equal to that of the liquid
density is greater than that of the liquid
mass is less than that of the liquid
Correct answer is A
No explanation has been provided for this answer.
0.18N
0.57N
0.75n
0.93N
Correct answer is B
Volume immersed solid = 3 x 105 x 23
= 2 x 105m3
Mass of liquid displaced = ev
= 2 x 105 x 900 = 18 x 107 kg
Upthrust = 18 x 107 x 10
= 7.8 x 109N
Mass of solid = ev
= 2.5 x 103 x 105
= 7.5 x 108
Weight of solid = 7.5 x 108 x10 = 7.8 x 109
Reading = 0.75 - 0.18 = 0.57N
