Question

If n electrons from a neutral solid sphere are transferred to another solid sphere having m electrons (m $>$ n), then the charges on the respective spheres are (e = charge of an electron)

• A. +ne and -(m-n)e
• B. -ne and +(m-n)e
• C. +ne and +(m-n)e
• D. +ne and -(m+n)e
• E. -ne and -(m+n)e

Hint:

Total charge is conserved.
Initial total charge = \( 0 + (-me) = -me \).
Final total charge = \( +ne + [-(m+n)e] = ne - me - ne = -me \).
This confirms the conservation of charge.

Answer 1

The Correct Option is D
