How do you find the electric field at the center of a sphere?
The electric field of a conducting sphere with charge Q can be obtained by a straightforward application of Gauss’ law. Considering a Gaussian surface in the form of a sphere at radius r > R , the electric field has the same magnitude at every point of the surface and is directed outward.
How do you find the electric potential energy of a sphere?
This energy can also be written as U=12CV2. we can immediately get from Eq. (8.9) the energy of a charged sphere, U=12Q24πϵ0a. This, of course, is also the energy of a thin spherical shell of total charge Q and is just 5/6 of the energy of a uniformly charged sphere, Eq.
What is the value of potential at the centre of hollow sphere?
Since the electric potential on the surface of a hollow sphere is 10 V and the electric field intensity inside the sphere is zero so the electric potential at the center of the sphere is also 10 volt.
What is the potential at the surface of that sphere?
The electric potential on the surface of a sphere of radius R and charge 3×10−6C is 500V.
What is the electric potential V at the center of the square?
The answer is -4 V. The potential at the center of the square is the sum of the potentials due to the four individual charges.

Why is the electric field zero at the center of the 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.
Why is the electric potential inside a sphere not zero?
Since all the charge is distributed on the surface of the spherical shell so according to Gauss law there will not be any electric flux inside the spherical shell, because the charge enclosed by the spherical shell is zero, so there will not be any electric field present inside the spherical shell.
What is the magnitude of the electric field inside the sphere?
The magnitude of the electric field inside ( r < R ) the sphere is E = AR^3Xε0 .
What is the potential at the center of a spherical shell?
Since there is no field inside the shell, the potential at any point inside the shell is equal to the potential on the surface of the shell, V=Q4πϵ0.
Can the potential of a non uniformly charged sphere be the same as that of the point charge?
The electric potential at any point p distant r from the point charge is V = kQ/r. So the potential of the non-uniformly charged sphere can be the same as that of a point charge.
What is the potential difference at Centre of hollow sphere?
According to Gauss’ law, there is no electric field inside a hollow conducting sphere, so moving a charge from the surface to the center takes no work. Therefore the potential difference between the surface and the center must be zero.
