1. Consider the situation shown below, if the rod is removed
1 point
A is -vely charged, B is +vely charged
both A and B are charged identically
both A and B are neutral
the situation will remain frozen
Clear selection
2. In the situation shown below, if A and B are separated, and then the rod is removed
1 point
A will be -vely charged
B will be +vely charged
A and B will be neutral
A and B will be charged identically
3. Consider the situation shown below, if B is earthed while the rod is there
1 point
A and B will both have -ve charge
A will have -ve charge
None of A and B will have charge
A will be negative, B will be +ve
Clear selection
4. In the situation shown, B is earthed, and then the rod is removed
1 point
A would be -ve, B would be +ve
Both A and B are -ve
Both A and B will be neutral
Clear selection
5. In the situation shown, B is earthed, then A and B are separated, and then the rod is removed (assume A to be big, B to be free from the effect of rod)
1 point
A will be -ve, B will be +ve
A will be -ve, B will be neutral
Both A and B are -ve
Both A and B are neutral
Clear selection
6. In the situation shown, B is earthed, and then the earthing is removed. Now the rod is also removed. Finally A and B are also separated
1 point
Both A and B are -ve
Both A and B are neutral
A is -ve, B is +ve
nothing can be predicted

7. In the situation shown below, when the rod is removed
1 point
Sphere has left side -ve
Sphere has right side positive
Sphere has no net charge anywhere
Anything can happen to charge once the rod is removed
Clear selection
8. In the above question if the sphere is connected to earth from right, then the rod is removed
1 point
the sphere will have +ve charge on it
the sphere will be neutral
can't be predicted
Clear selection
9. In the above question if the sphere is connected to earth from right, then the earthing is removed followed which the rod is removed
1 point
the sphere will have +ve charge on it
the sphere will be neutral
can't be predicted
Clear selection
10. In the above question, if the sphere is earthed from left, instead of earthing on right (and the rod is removed after earthing is removed)
1 point
Now the sphere will be left with -ve charge
the sphere will still be left with positive charge
the sphere will be neutral
nothing can be predicted
