## How do you find the magnitude of the electric field outside the sphere?

So we can say: The electric field is zero inside a conducting sphere. The electric field outside the sphere is given by: E = kQ/r2, just like a point charge.

**What is the electric field outside a spherical conductor?**

The electric flux is then just the electric field times the area of the spherical surface. The electric field outside the sphere (r > R)is seen to be identical to that of a point charge Q at the center of the sphere.

**What is the formula of electric field of sphere?**

The magnitude of the electric field inside ( r < R ) the sphere is E = AR^3Xε0 .

### What is the electric field outside the surface of the spherical shell?

Thus, the electric field outside a Shell is the same . The charge enclosed inside the spherical shell is 0. Therefore, due to the electric field, the uniformly charged spherical shell is zero at all points inside the shell.

**How do you find the magnitude of an electric field?**

We can use the equation E = k | Q | r 2 E = k | Q | r 2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge, which is negative in this case. E = k | Q | r 2 = ( 8.99 × 10 9 N ⋅ m 2 /C 2 ) | − 1.5 × 10 − 9 C | ( 0.035 m ) 2 = 1.1 × 10 4 N/C.

**What is the magnitude of electric field?**

The magnitude of the electric field is simply defined as the force per charge on the test charge. The standard metric units on electric field strength arise from its definition. Since electric field is defined as a force per charge, its units would be force units divided by charge units.

## What is the charge on the outer surface of the outer sphere?

As the solid sphere has charge +2Q, the equal and opposite charge induced on inner and outer surface on the hollow sphere. Since net charge inside is zero so the charge on the inner surface of the hollow sphere is −2Q and +2Q charge also induced on outer surface. So net charge on outer sphere is −7Q+2Q=−5Q.

**What is the electric field around a charged sphere?**

If we assume any hypothetical sphere inside the charged sphere, there will be no net charge inside the Gaussian surface . So, Σq = 0 . So, the net flux φ = 0. So, the electric field inside a hollow sphere is zero.

**What is the magnitude of electric field intensity inside a charged spherical shell?**

Since charge enclosed inside the spherical shell is zero. Hence, the electric field due to a uniformly charged spherical shell is zero at all points inside the shell.

### What is the magnitude of the electric field at the point?

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/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

**What is E kQ R 2?**

The formula E=kQr2 is the electric field of a point charge in radial direction at a distance r from the charge. This means, especially, that the field is not homogeneous, i.e. not the same at every point in space.

**Is electric field zero inside a sphere?**

All the charges lie on the surface of the charged sphere. If a gaussian surface is drawn within the sphere, there will not be any charge within the surface. Therefore, the electric field strength inside a sphere is zero.

## What is the magnitude of a electric field at a point inside a charged spherical shell?

**What will be the electric field at a point inside the charged sphere?**

They exactly cancel out, and hence for any point inside the sphere, the value of electric field is exactly zero.

**What is magnitude of electric field?**

The magnitude of the electric field is simply defined as the force per charge on the test charge. If the electric field strength is denoted by the symbol E, then the equation can be rewritten in symbolic form as . The standard metric units on electric field strength arise from its definition.
