Calculate (i) Weight of solid in SJ system. (ii) Upthrust on solid in SI system. (iii) Apparent weight of solid in alcohol. (iv) Will the apparent weight of solid be less or more, if it is immersed completely in brine solution? Give a reason. [g = 10 ms-21 40.5 N (ii) 12 N (iii) 28.5 N (iV) It will weigh less] 2. A stone of density 3000 kgm-3 is lying submerged in water of density 1000 kgm-3. If the mass of tone in air is 150 kg, calculate the force required to lift the stone. [g = 10 ms-21 [1000 N) . A solid of area of cross-section 0.004 m2 and length 0.60 m is completely immersed in water of density 1000 kgm 3 Calculate : (i) Wt. of solid in SI system (ii) Upthrust acting on the solid in SI system. (iii) Apparent weight of solid in water. (iv) Apparent weight of solid in brine solution of density 1050 kgm-3.
