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?

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

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
