Question

Two small metal spheres A and B have different electric potentials (A has a higher potential).
Describe mathematically what happens if you connect them with a wire. Let the charges of the two spheres after connection be qA and qB and radiuses be RA and RB.
Express your answer in terms of the variables RA and RB.

Describe in words what happens if you connect them with a wire.

A. If the two spheres have the same radius, then positive charge must flow from B to A

B. If the two spheres have the same radius, then positive charge must flow from A to B.

Explanation / Answer

when two Sphere A and B having diff potnetials are connected,

redistirbution of charge takes place accordingly to the proportions of radius

as E = KQ/r^2

amount of charge deposited is direclty proprotioanl to Radius R

i.e larger the radius, larger the quantity of charge

-----------------------

part A:

if both Spheres are of same Raidus, then tranfer of charge takes place from high potential to,ow potnetial sphere

i.e from +ve Sphere to -ve sphere

this continus till both the sphere attians equillibirum point

i.e
B. If the two spheres have the same radius, then positive charge must flow from A to B.:
