Practice question

**Electric field concept** visualizes influence of source charge. Uniform field exerts constant force F = qE, and flux Φ = E·A = E A cosθ links field to area orientation, maximum when field normal to surface. The wire’s linear charge distribution leads to a cylindrical field pattern ( 1/r ), as per Gauss’s law, spreading over a surface area proportional to r . A point charge’s spherical spread ( 1/r² ) over r² results in a faster drop-off. Substituting values gives Linear distribution, which matches expected magnitude for this electrostatic configuration, confirming Coulomb's and Gauss's principles and charge quantization consistency.
