Solid weighs 0.040 N in air and 0.024 N when fully immersed in a liquid of density 800 kg m-3. What is the volume of the solid? (g = 1Oms2)
A
2.0 x 10-6m3
B
2.5x10-6m3
C
3.0x10-6m3
D
2.0x 10-5m3
correct option: a
Upthrust = weight fluid displacement 0.040 - 0.024 = PVg
0.016 = 800 x V x 10
V = 2.0 x 106
