Voltage on a electrostatic charged sphere

AI Thread Summary
Voltage on an electrostatically charged sphere is determined by the formula q*k/r, where q is charge, k is a constant, and r is the radius. When a metal box contacts a charged sphere at 100 kV, the voltage relative to the box depends on its position and grounding. If the box is grounded, it will not maintain the same voltage as the sphere. Applying voltage from a battery to a metallic object can induce a small static charge, but this charge will be minimal. Understanding the relationship between charge, voltage, and grounding is crucial in these scenarios.

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).
