Question

For an isolated positive charge, how do the electric field lines extend into space?

Options

• Lines form closed loops around the charge

• Lines remain confined within a finite spherical region

• Lines converge inward from all directions

• Lines radiate outward to infinity

Answer 1

For an isolated positive charge with no negative charge nearby, the electric field lines radiate outward symmetrically in all directions extending to infinity. This pattern reflects the fact that there is no negative charge available to terminate the lines, so they extend indefinitely. The density decreases with distance following the \[1/r^2\] law.
