The capacitance of a capacitor between` 4//3` times its original value if a dielectric slab of thickness `t=d//2` is inserted between the plates (d is the separation between the plates). What is the dielectric consant of the slab?

The capacitance of a capacitor between` 4//3` times its original value

1.	The capacitance of a capacitor between` 4//3` times its original value if a dielectric slab of thickness `t=d//2` is inserted between the plates (d is the separation between the plates). What is the dielectric consant of the slab?
Answer» `(epsilon_(0)A)/([d-(d)/(2)+(d)/(2k)])=(4)/(3)(epsilon_(0)A)/(d)` or `(1)/((d)/(2)(1+(1)/(K)))=(4)/(3d)` on solving we get `K=2`

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.
