A charge is kept close to a metal sphere of radius R.What is the potential at point P at a distance R/2 above the centre due to charges induced on the sphere?

anything multiplied by zero will give always a zero result....

maybe if place a charge -q a charge +q will be induced on the surface of sphere. Since the sphere has uniforf surface the surface charge density will be same on sphere.now this is lyk condtng sphere given a charge whose potential is q/4pi eo uniformly inside itq

potential remains same inside a conducting sphere...

TOTAL V at centre =kq/x+kQ/R-kQ/R=kq/x

Q=CHARGE INDUCED..

now V at centre=V at point P

V at P=kq/(R/2^2+x^2)^1/2 +V'

V'=V by induced charges at P

so    kq/x=V'+ kq/(R/2^2+x^2)^1/2

we get  V'
