The potential due to a charge Q is .

 
As seen from the above equation, potential is inversely proportional to the distance r from the centre.
Thus, a sphere with smaller radii will have a larger potential.

If two spheres of different radii have equal charge, then the potentia...
Explanation:
When two spheres of different radii have equal charge, the potential will be more on the smaller sphere. This can be explained using the equation for electric potential.

Electric potential:
The electric potential at a point in space is given by the equation V = kQ/r, where V is the electric potential, k is the electrostatic constant, Q is the charge, and r is the distance from the charge.

Relation between potential and radius:
In the case of two spheres with equal charge, the charge Q is the same for both spheres. However, the radius of the spheres is different. Let's assume that the radius of the smaller sphere is r1 and the radius of the larger sphere is r2.

Comparison of electric potential:
Since the charge is the same for both spheres, the only difference in the electric potential equation is the distance from the charge. As the distance from the charge decreases (i.e., when the radius is smaller), the electric potential increases. Therefore, the electric potential will be more on the smaller sphere.

Reason:
The reason for this is that the electric potential is inversely proportional to the distance from the charge. When the radius of the sphere is smaller, the distance from the charge is smaller, leading to a higher electric potential. On the other hand, when the radius of the sphere is larger, the distance from the charge is larger, resulting in a lower electric potential.

Conclusion:
Therefore, when two spheres of different radii have equal charge, the electric potential will be more on the smaller sphere. This is because the electric potential is inversely proportional to the distance from the charge, and the distance is smaller for the smaller sphere.

When equal charges are given to two spheres of different radii, the potential will be more or the smaller sphere as per the equation, Potential = Charge / Radius.
Since potential is inversely proportional to radius, the smaller radius will have higher potential and vice versa.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Negative Refractive Index: One of the most fundamental phenomena in optics is refraction. When a beam of light crosses the interface between two different materials, its path is altered depending on the difference in the refractive indices of the materials. The greater the difference, the greater the refraction of the beam. For all known naturally occurring materials the refractive index assumes only positive values. But does this have to be the case?In 1967, Soviet physicist Victor Veselago hypothesized that a material with a negative refractive index could exist without violating any of the laws of physics.Veselago predicted that this remarkable material would exhibit a wide variety of new optical phenomena. However, until recently no one had found such a material and Veselago’s ideas had remained untested. Recently, meta-material samples are being tested for negative refractive index. But the experiments show significant losses and this could be an intrinsic property of negativeindex materials.Snell’s law is satisfied for the materials having a negative refractive index, but the direction of the refracted light ray is ‘mirror-imaged’ about the normal to the surface.There will be an interesting difference in image formation if a vessel is filled with “negative water” having refractive index – 1.33 instead of regular water having refractive index 1.33.Say, there is a fish in a vessel filled with negative water. The position of the fish is such that the observer cannot see it due to normal refraction since the refracted ray does not reach to his eye.But due to negative refraction, he will be able to see it since the refracted ray now reaches his eye.Q. When the angle of incidence will be equal to angle of refraction for material having negative refraction index?
