SUMMARY

The electric field inside a uniformly charged sphere is zero, regardless of the charge or radius. In this discussion, the given parameters are a radius of 10 cm and a charge of 0.4 µC. The user calculated the electric field just outside the sphere to be 360,000 V/m using the formula E = kq/r², where k is the Coulomb's constant. However, the electric field inside the sphere remains zero due to the symmetrical distribution of charge.

PREREQUISITES
  • Understanding of Coulomb's Law and electric fields
  • Familiarity with the concept of electric field inside conductors
  • Knowledge of basic electrostatics principles
  • Ability to apply mathematical formulas for electric fields
NEXT STEPS
  • Study the properties of electric fields in conductors and insulators
  • Learn about Gauss's Law and its application to spherical charge distributions
  • Explore the concept of electric potential in relation to electric fields
  • Investigate the effects of varying charge distributions on electric fields
USEFUL FOR

Students studying physics, particularly those focusing on electrostatics, as well as educators teaching electric field concepts and applications.

Homework Statement



what is the magnitude and direction of the electric field just inside the sphere?
givens: radius=10cm charge=.4uC

Homework Equations



E=kq/r^2

The Attempt at a Solution


i found that the electric field just outside the sphere is 360000vm^-1
i just don't know how to find the field on the inside of the sphere
