During a charging process by induction, a positively charged rod is brought closed to a neutral metal sphere mounted on an insulated stand without touching it. Then, the metal sphere:
- A.becomes positively charged, whenever it is grounded.
- B.loses some electrons, whenever it is grounded.
- C.gains some electrons, whenever it is grounded.
- D.gains some protons whenever it is grounded.
መልሱን እና ማብራሪያውን ይመልከቱ
መልስ፦ C gains some electrons, whenever it is grounded.
ለምን
During induction, when a positively charged rod is brought near a neutral metal sphere and the sphere is grounded, free electrons from the ground flow to the sphere to neutralize the positive charge on the side opposite the rod, making the sphere gain electrons.
