Voltage on a electrostatic charged sphere

  1. Jan 23, 2014 #1
    I understand that voltage depends on how far the electrons are, so for a sphere it would be q*k / r.
    But what if a sphere with 100kv , then we put with contact to it a metal box , becoming on body, will the volt remain 100kv

    100kV relative to what?
    What is the position of the box relative to the sphere?

    I guess no, but for me it is not clear what you want to measure.

    Hello people... Charged body has an voltage.. But the reverse...can applying voltage to a metallic object from a battery who's other terminal is grounded produce static charge on that metallic object??

    Yes (but the charge will be tiny with batteries).
