Question

Hi I'm given the diameter of the sphere is 25cm. An electric pen brought near this sphere causes a voltage of 5000 V. The distance between the sphere and the pen is 14cm. The pen itself is measured at 25cm.

they want to know what is the charge on the sphere?

Please break it down so I can understand. The last answer had the wrong diameter calculated into the problem and was missing what formulas they used for each problem and how they solved it in steps.

Expert Solution

Introduction:

The voltage difference is the difference in the voltage at the near end and farther end of the pen.

The voltage difference,

The distance from the near end to the centre is r+d and the distance from the far end to the centre is r+d+l
