Answer 1

The magnitude of the electric field at point p within an electric field generated by a linear charge distribution is calculated using Coulomb's law and the concept of electric field, expressed as E = k × |Q| / r², and involves integration across the charge distribution.

Step-by-step explanation:

To determine the magnitude of the electric field at point p, we can use Coulomb's law and the definition of the electric field. The force F between two charges is given by Coulomb's law as F = k × |qQ| / r², where k is Coulomb's constant, q and Q are the charges, and r is the distance between the charges. In the context of an electric field, this formula can be expressed in terms of the electric field E as E = k × |Q| / r² for a point charge Q. In this scenario, we are given k = 1/(4πε0), and it is understood that the point p is within an electric field generated by a linear charge distribution with charge density λ, length l, and distance d.

To find the electric field at point p, we would need to integrate the contribution of electric field from each infinitesimal piece of the charge distribution, considering their respective distances from point p. Without the specifics of the charge distribution geometry (e.g., a line, ring, or plane), the exact integration process would vary. However, the electric field would generally be expressed in terms of k, λ, the geometry dimensions (like l for length), and the distance d from the charge distribution.

Answer 2

The strength of the electric field is generally equal to

E = F/Q

However, this could be modified in terms of charge and distance,d.
E = kQ/d²
The k is actually a constant which is equal to 1/4π∈₀

Since no given quantitative data, the answer should just be E = kQ/r².
