1why poential is constant inside the sphere? V=kq/r......................r is not same at evry point inside sphere
what is the electrostatic potential at a distance r from the center of a charged metallic sphere of radius R(r<R).................Plz show thw graph of potential with distance also.

11The Electric Field inside in the conductor (metallic sphere ) is 0. Therefore rate of change of potential is 0. therefore the potential is constant the potential at the surface will be the potential at any point inside the sphere

39@sumit : u have got a wrong conception, what cirang has said is correct.
it is constant because electric field is 0 inside a sphere.
so V should be constant.
1electric fieldis zero..........so why cant potential be zero too!!!!
39E=\frac{dV}{dr}
so if E=0 then \frac{dV}{dr}=0
this means V is a constant
39i suggest u better read up this electrostatics topic from HC VERMA and NCERT.
1sumit.......why poential is constant inside the sphere? V=kq/r......................r is not same at evry point inside sphere
here V=kq/R...wher R = radius of d sphere.....
V=kq/R.........if r<R
V=kq/r..........if r>R
