How can we charge two metallic spheres with equal and opposite charge using the method of induction?

Explanation

To charge two metallic spheres with equal and opposite charges using the method of induction, follow these steps:

### Step-by-Step Solution:

1. **Setup the Spheres**: Place two metallic spheres on insulating stands. Ensure that they are not touching each other and are positioned close enough to influence each other.

2. **Introduce a Charged Object**: Bring a charged object (which can be positively or negatively charged) close to one of the metallic spheres. Make sure that this charged object does not touch the spheres.
