Question

An identical uncharged sphere touches a charged metallic sphere carrying charge \[q\]. What charge does each sphere have after contact?

Options

• \[2q\]

• \[q/4\]

• \[q\]

• \[q/2\]

Answer 1

The charge redistributes equally because the spheres are identical. By symmetry, each sphere has charge \[q/2\] after contact.
