question

A solid, metal object is isolated from other charges and has charge distributed on its surface. The charge distribution is not uniform. It may be correctly concluded that the

physics

options

  1. the electric field inside the object, but very close to the surface, is equal to the surface charge density at any location divided by the permittivity of free space
  2. the electric field outside the object, but very close to the surface, is equal to the surface charge density at any location divided by the permittivity of free space
  3. the electric field inside the object is directly proportional to the distance away from the center of mass of the object
  4. electric field outside the object is zero
  5. the electric field outside the object is inversely proportional to the distance away from the center of mass of the object
  6. the electric field outside the object, but very close to the surface, is equal to the permittivity of free space divided by the surface charge density at any location
  7. the electric field outside the object, but very close to the surface, is inversely proportional to the surface charge density at any location divided by the permittivity of free space
  8. the electric field outside the object is equal to the electric field inside the object
  9. the electric field inside the object is zero
  10. the electric field outside the object is directly proportional to the distance away from the center of mass of the object
