Practice Maharashtra HSC (Class 12) Electrostatics in the app →Gauss' law in electrostatics relates the closed-surface flux of electric field to theElectric field at a point INSIDE a uniformly charged spherical shell isOutside a uniformly charged sphere the field magnitude at distance r from centre is equivalent to that ofA 10 cm sphere carries charge 1 μC. The field magnitude at 30 cm from its centre isField due to an infinite uniformly charged plane sheet of surface charge density σ isElectric field on the surface of the 10 cm sphere of question above isEquipotential surfaces of a point charge areCapacitance of a parallel-plate capacitor with plate area A, separation d and a dielectric of constant K isTwo capacitors C₁ = 2 μF and C₂ = 3 μF are connected in series across a 10 V battery. The charge on each capacEnergy stored in a 5 μF capacitor charged to 100 V is
