Eshan Sir …

But in our problem, sphere given.

You told E

electric field is dependent on r in sphere ,

But here E independent on r, how sir..please once explain.

Electrostatics question based on earthing of spherical shell

an object has a charge of 2c and gains 10^19 electrons. the net chaarge on the object becomes??

A wire with a linear charge density lambda forms a quarter of a cjrclenof radius R and is placed asa shown in thefigure with its centre of curvature at the origin O the electric field at O will be
