Physics Question on Electric Charge
Two identical metal spheres A and B are supported on insulating stands and placed in contact. What kind of charges will A and B develop when a negatively charged ebonite rod is brought near A?
A
A will have a positive charge and B will have a negative charge
B
A will have a negative charge and B will have a positive charge
C
Both A and B will have positive charges
D
Both A and B will have negative charges
Answer
A will have a positive charge and B will have a negative charge
Explanation
Solution
In contact, A and B behave as one body. Therefore, by induction, positive charge developes on A and negative charge developes on farther side of B.
