The electric field intensity (E) at a distance of 3 m from a uniform long straight wire of linear charge density 0.2 m Cm ⁻¹ is
Options
- A1.2 10^3 Vm ⁻¹
- B0.6 10^3 Vm ⁻¹
- C1.8 10^3 Vm ⁻¹
- D2.4 10^3 Vm ⁻¹
Correct answer
A. 1.2 10^3 Vm ⁻¹
Step-by-step solution
The electric field at a distance r from a uniform straight wire is aligned & E = 2 k r = 2 9 10^9 0.2 10⁻⁶ 3 & =1.2 10^3 Vm ⁻¹ aligned
