An air filled spherical capacitor has a potential difference V = 1,279V between the surfaces. The inner radius is ra =26.3mm and the outer radius is r = 29mm. Determine the energy density at the point = 27.8mm. (in)

Equ-Potential lab.pdf Work done can also be determined by considering movement across equipotentials. This can be written as: AW by you = q(Vp2 – VP1). VPi is the electric potential at point Pi. This tells us that the work done by you is dependent only on the magnitude and type (+ or -) of the electric charge you are trying to move, and the difference in electric potential from the ending point to the starting point. Both of these equations could yield positive or negative values for work. Positive work for you means that you (or some outside influence) are doing work against the field to move the charge. Negative work for you means that you aren’t doing any work and the particle moves the way the field would naturally push or pull the charge. 3) Use the equations above that determines work and your sketches (for electric fields and equipotentials) to state if each of the situations below would be + or - work: a) Moving a + charge from a point of higher electric potential to one of…

A positive charge of 6 micro-coulomb is located at the point (2, 2) meters (in the Cartesian coordinate system). Calculate the electric potential at the point (8, 6) meters. Write your answer in kilo-volts.
