Question

Two conducting spheres of different radii, as shown above, each have charge +Q. Which sphere has a higher electric potential at its surface? the large sphere the small sphere same, and neither is zero same, and both are zero If a conducting wire connects the two spheres, which of the following is true? Protons flow from the big sphere to the little sphere until the spheres have the same surface potential. Protons flow from the little sphere to the big sphere until the spheres have the same surface potential. Electrons flow from the big sphere to the little sphere until the spheres have the same surface potential. Electrons flow from the little sphere to the big sphere until the spheres have the same surface potential.

Explanation / Answer

(8) Electric potential inversely proportional to the distance from the center i.e radius. Hence, electric potential is more in the case of small sphere. Ans: Option - (B) (9) Electrons flow from low to high potential. So, electrons flow from the big sphere to the little sphere until the spheres have the same surface potential. Ans: Option - (C)
