Question

The electric field strength of an infinite line of charge decreases with distance r as ____?

1) 1/r
2) 1/r²
3) r
4) r²

Answer 1

The electric field strength of an infinite line of charge decreases with the distance as 1/r, due to its dependence on linear charge density and inverse proportionality to distance.

Step-by-step explanation:

The electric field strength of an infinite line of charge decreases with distance r as 1/r. This relationship differs from the electric field of a point charge, which decreases as 1/r². In the case of an infinite line of charge, the electric field is directly proportional to the linear charge density and inversely proportional to the distance from the line of charge.
