How much of potential energy stored in conducting sphere

Click For Summary
SUMMARY

The potential energy stored in an isolated conducting sphere with a radius of 6.85 cm and a charge of 1.25 nC is calculated using the formula for capacitance, C = 4πER, where E is the permittivity of free space. The resulting potential energy is determined to be 103 nJ. This conclusion is based on the application of electrostatic principles relevant to conducting spheres.

PREREQUISITES
  • Understanding of electrostatics and electric potential energy
  • Familiarity with the concept of capacitance and its formula
  • Knowledge of the permittivity of free space (E)
  • Basic algebra for solving equations
NEXT STEPS
  • Research the derivation of the capacitance formula for spherical conductors
  • Learn about the relationship between charge, voltage, and energy in capacitors
  • Explore the concept of electric fields around charged conductors
  • Study the applications of potential energy in electrostatics
USEFUL FOR

Students studying physics, particularly those focusing on electrostatics, as well as educators looking for practical examples of potential energy calculations in conducting spheres.

Hi,
can anyone help me to solve this problem...

An isolated conducting sphere which radius R is 6.85cm has a charge q=1.25nc. Determine how much potential energy stored in conducting sphere?

I try to solve it but can't get the ans...the hint given is by using c=4(pi)ER
answer is =103nJ

thanks for helping
