a glass rod rubbed with silk is brought close to two uncharged metallic spheres A and Btouching each other. the rod induces charges on A and B . tell what happens when:
1) A and B are slightly separated
2) the glass rod is then taken away
3) A and B are separated far apart
( explain also)
Here laws of induction will follow...
(1) If they are slightly separated...
When a positively charged rod is brought close to two touching metallic spheres A and B, then negative charge will be induced on the nearer A sphere and positive charge will appear on the far side of sphere B.
.
(2) If the glass rod is taken away...
No charges will be present as the source induction is removed and charges will relocate to their original positions.
.
(3) If A and B are separated far apart...
In this case there will be no influence of one sphere on another and thus no charges will be present on either.
