A solid object of weight 5.0 N is suspended from a force meter. Its volume is 200 cm3. It is fully immersed in oil of density 800 kg/m3 without touching the container. Take g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg. Neglect upthrust in air. What is the force meter reading?
1.6 N1.6\ \mathrm{N}1.6 N
5.0 N5.0\ \mathrm{N}5.0 N
6.6 N6.6\ \mathrm{N}6.6 N
3.4 N3.4\ \mathrm{N}3.4 N
