Questions
An iron casting has a large cavity in it. If weighs 6000 N in air and 4000 N in water. If density of iron is 8 and density of water is 1 , find the volume of cavity in the casting.
detailed solution
Correct option is B
B = Buoyant force = (6000 - 4000) N = 2000 N∴ Volume of casting =20001000×10n3=0.2 m3Volume of iron in the casting =60008000×10n3=0.075 m3∴ Volume of cavity =(0.2−0.075)m3=0.125 m3Talk to our academic expert!
