An infinite line charge produce a field of 7.182×108  N/C7.182 \times {10^8}\;N/C at a distance of 2  cm.2\;cm. The linear charge density is
View answer and explanation
Correct option: B
7.98×10−4  C/m7.98 \times {10^{ - 4}}\;C/m
Option B (7.98×10−4  C/m7.98 \times {10^{ - 4}}\;C/m) is correct because it is calculated directly from the formula for the electric field due to an infinite line charge.
