JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium
1 of 1
Understanding +4 | -1
Electric field intensity at a point outside uniformly charged thin infinite plane sheet is 'E1\text{E}_1'. The electric field intensity at a point near and outside the surface of a positively charged conductor of any shape is 'E2\mathrm{E}_2'. The relation between magnitude of E1\text{E}_1 and E2\text{E}_2 is (assumed air as the medium)
View answer and explanation
Correct option: A
2E1=E22 \mathrm{E}_1=\mathrm{E}_2
Option A is correct because the electric field intensity near a charged conductor is twice the electric field intensity of an infinite plane sheet with the same charge density.
