1.	A light rod length `L`, is hanging from the vertical smooth wall of a vehicle moving with acceleration `sqrt(3)g` having a small mass attached at its one end is free to rotate about an axis passing through the other end. The minimum velocity given to the mass at its equilibrium position with respect to vehicle so that it can complete vertical circular motion respect to vehical) is `sqrt(KgL)`. Find the value of `K`.
Answer» Correct Answer - 8 `g_("eff") = sqrt(g^(2) + a^(2)) = sqrt(g^(2) + 3g^(2)) = 2g` `V_(min)` at equilibrium position `= sqrt(4g_(eff)l)` `= sqrt(4(2g)l)` `= sqrt(8gl)`

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
