A U tube with both ends open to the atmosphere is partially filled with water. Oil which is immiscible with water is poured into one side until it stands at a distance of 10 mm above the water level on the other side. Meanwhile the water rises by 65 mm from its original level (see diagram). The density of the oil is 425 kg m−3425\ \text{kg m}^{-3} 800 kg m−3800\ \text{kg m}^{-3} 928 kg m−3928\ \text{kg m}^{-3} 650 kg m−3650\ \text{kg m}^{-3}

Multiple Choice Options

  • A 425 kg m −- _ 3
  • B 800 kg m −- _ 3
  • C 928 kg m −- _ 3
  • D 650 kg m −- _ 3
