1.	A silver ingot weighing 2.1 kg is held by a string so s to be completely immersed in a liquid of relative density `0.8`. The relative density of silver is `10.5`. The tension in the string in `kg-wt` isA. `1.6`B. `1.94`C. `3.1`D. `5.25`
Answer» Correct Answer - B Apparent weight `=V(rho-sigma)g =(M)/(rho) (rho-sigma)g = M(1-(sigma)/(rho))g = 2.1(1-(0.8)/(10.5))g = 1.94 g` Newton `= 1.94 kg-wt`

Figure shows a cubical block of side 10 cm and relative density 1.5 suspended by a wire of cross sectional area `10^(-6) m^(2)`. The breaking stress of the wire is `7 xx 10^(6) N//m^(2)`. The block is placed in a beaker of base area `200 cm^(2)` and initially i.e. at t = 0, the top surface of water & the block coincide. There is a pump at the bottom corner which ejects `2 cm^(3)` of water per sec. Find the time at which the wire will break.
