To understand the electric potential and electric field of a point charge in three dimensions Consider a positive point charge q
, located at the origin of three-dimensional space. Throughout this problem, use k in place of 14?
1 answer:
Answer:
The magnitude of the electric field at distance r from the point charge q is 
Explanation:
Suppose, Find E(r), the magnitude of the electric field at distance r from the point charge q.
We know that,
The electric field is proportional to the point charge and inversely proportional to the square of the distance from the charge point .
In mathematically,

Where, q = charge point
R = distance from charge point
Hence, The magnitude of the electric field at distance r from the point charge q is
