Question

11.If 2500 electrons are removed from an isolated neutral metal sphere, what is the charge acquired by the sphere

Answer 1

Answer:

charge on single electron = -1.6 × 10 ‐¹⁹

and then charge on 2500 electrons will be (-1.6×10‐¹⁹)×(2500) = -40×10‐¹⁹

so the final charge accquired by sphere is 0-(-40×10‐¹⁹)=40×10‐¹⁹C
