1.	Three positive charges each having the value q are placed at the vertices of an equilateral triangle. The resulting lines of force should be sketched as
Answer» Correct Answer is: (c) The tangent drawn to a line of force at any point on it must give the direction of the electric intensity at that point. Consider a point midway between any two of the charges. Here, the resultant intensity is only that due to the third charge and must point away from the third charge. This is satisfied only in the sketch (c).

Answer»

Correct Answer is: (c)

The tangent drawn to a line of force at any point on it must give the direction of the electric intensity at that point. Consider a point midway between any two of the charges. Here, the resultant intensity is only that due to the third charge and must point away from the third charge. This is satisfied only in the sketch (c).

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.
