A beaker containing water is placed on the platform of a spring balance. The balance reads 15N. A stone of mass 0.5kg and density 500 kg /m' is kept fully ). immersed in water without touching walls of beaker and held at rest. What will be the balance reading now? (g = 10m /s) 1) 20 N A solid object is immersed in water in a vessel by a string attached to the base, immediately on cutting the string, the object travels 1 m in 1 sec. The relative density of solid is (g = 10 m/s) 2) 25 N 3) 10 N 4) 15 N 1 1) 3 2) 4 7 3) 6. 4) 8 28. Two spherical balls of radius r and r, and of density p are tied up with a long string and released in a non-viscous liquid column of lesser density o with the string just taut as shown. Find the tension in the string. 4 4 - r 4 1) 4 1. 3) ( .3 4) zero
