## How do you find the maximum electric field by the sphere?

A non-conducting sphere of radius a carries a non-uniform charge density. The electrostatic field inside the sphere is a distance b from is center and is given by **E = (b/a) ^{4}E_{}** (E

_{}being the maximum magnitude of the field.)

## What is the magnitude of the electric field along the surface?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation **E = kQ/r ^{2}**, where k is a constant with a value of 8.99 x 10

^{9}N m

^{2}/C

^{2}.

## How do you find the maximum electric field?

Since the voltage and plate separation are given, the electric field strength can be calculated directly from the expression **E=VABd E = V AB d** . Once the electric field strength is known, the force on a charge is found using F = qE.

## How do you find the maximum value of an electric field?

Formula used:

**E=kqx(x2+R2)32** where R is radius of circle, E is electric field intensity, q is a charge and x is the distance between the center of ring and the field intensity.

## How do you find the magnitude of an electric field at a point?

The magnitude of the electric field E created by a point charge Q is **E=k|Q|r2 E = k | Q | r 2** , where r is the distance from Q. The electric field E is a vector and fields due to multiple charges add like vectors.

## What is the magnitude of the electric field on the surface of a sphere of radius r having uniform surface charge density σ?

**σ/2ϵ0**

## What is the magnitude of the electric field just inside the surface of the sphere?

Gauss’ law tells us that the electric field inside the sphere is **zero**, and the electric field outside the sphere is the same as the field from a point charge with a net charge of Q. This result is true for a solid or hollow sphere. So we can say: The electric field is zero inside a conducting sphere.

## What is the formula for electric field strength?

The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply **E = F/q.**
