Answer» Correct Answer - [(A)PQR(B)QST(C)ST(D)PR] (A) Field remains same as charge is same Hence energy stored increases (P) & (Q) as field is same and (R) (B) Since distance between plate and charge remains same and field decreases (s&T) `F=(Q^(2))/(2 in_(0) A)` charge is same hence force remain same (Q) (C) Since connected to battery P.D remains same and as distance increases the electric field decreases (T) Also as capacitance decreases the charge also decreases decreasing the force of interaction (D) Capacitance increases and P.D remaining same, thus charge and energy increases (P) and force of interaction increases Field remains same as distance and P.D remains same (R) and energy increases as

Nature of climax community depends upon(A) Climate (B) Water (C) Soil fertility (D) Temperature
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. These bacteria convert atmospheric nitrogen into nitrogenous compound and fix in the soil.The organisms which enrich the nutrient quality of the soil are called(a) Microbes(b) Biofertilizers(c) Yeast(d) Biopesticides
