As we know that the electric field intensity inside the hollow spherical charged conductor is zero. Hence, the work done in moving a point charge inside the hollow spherical conductor is also zero. This implies that the potential difference between any two points inside or on the surface of the conductor is zero.
What is the potential at the centre of a 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.
What is the electric field intensity inside a hollow conductor?
The correct option is C) Zero.
A spherical Gaussian surface which lies just inside the conducting shell. Now, the Gaussian surface encloses no charge, since all of the charge lies on the shell, so it follows from Gauss’ law, and symmetry, that the electric field of the shell is zero.
What is the electric potential 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.
At what point electric potential is maximum?
In the case of an equipotential surface, the electric field at every point is always normal (to the direction of the electric field (E)). Therefore, the potential at point B is more than C and B. So, the potential at points are VB>VC>VA. Hence, the electric potential at point B is maximum.
What is electric field intensity?
A measure of the force exerted by one charged body on another. The electric field intensity (volts/meter) at any location is the force (Newtons) that would be experienced by unit test charge (Coulombs) placed at the location. …
What is the relationship between electric field intensity and electric potential?
The relation is very simple. Electric field intensity is equal to the negative of rate of change of potential with respet to the distance or it can be defined as the negative of the rate of derivative of potential difference, V with respect to r, E = – dV/dr.
How do you find the electric field at the center of a square?
Therefore, the electric field at the center of the square will be 4.7×106N/C. 4.7 × 10 6 N / C . As is seen from the above calculation, it is possible to use the equation E=kQd2 E = k Q d 2 for individual charges and add them to obtain the net electric field.
What is the electric potential at the center of the square of side 1m?
What is the electric potential at a point in an electric field?
Electric potential at a point in an electric field, is defined as the amount of work done in order to move a unit positive charge from infinity to that point along any path, against the electrostatic forces, with acceleration zero.
What is potential maximum?
1 the greatest possible amount, degree, etc. 2 the highest value of a variable quantity. 3 (Maths) a a value of a function that is greater than any neighbouring value.
Where is the electric field the maximum in a dipole?
It is maximum when p and E point in opposite direc ons, and minimum when they are parallel (note the minus sign). The dipole is “wound up” when it is opposing the field, ready to do work, and cannot do any more work when it is aligned with the field.
Is electric potential on dipole axis maximum?
The electric potential will be maximum at the dipole axis. … The electric potential will be zero at the perpendicular axis of the dipole.
