Consider a very large infinite plane sheet of uniform positive surface charge density σ. If P1 and P2 are two points at distances l and 2l from the sheet respectively, then the magnitude of electric fields E1 at P1 and E2 at P2 are:
- 1E1 = E2 = σ/ε0
- 2E1 = E2 = σ/(2ε0)✓
- 3E1 = 2σ/ε0, E2 = σ/ε0
- 4E1 = σ/ε0, E2 = σ/(2ε0)
Correct answer
E1 = E2 = σ/(2ε0)
