Consider the following statements associated with the basic electrostatic properties of ideal conductors:
1. The resultant field inside is zero.
2. The net charge density in the interior is zero.
3. Any net charge density in the interior is zero.
4. The surface is always an equipotential.
5. The field just outside is zero.
Of the statements:
-
- 1, 2, 3 and 4 are correct
- 3, 4 and 5 are correct
- 1, 2 and 3 are correct
- 2 and 3 are correct
Correct Option: A
Only statement 5 is not correct. The electic field, if any is radially outward at conducting surface governed by the relation, Dn = ρs, where Dn is the normal or radial component of electric displacement density and ρs is the surface charge density at the point of interest. Thus depending upon ρs, the field may be zero or non-zero.
