1why???????????
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
1why poential is constant inside the sphere? V=kq/r......................r is not same at evry point inside 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
