How will you give equal and opposite charge to two identical metal spheres on insulated stands ? You can use a charged rod but touching of rod to spheres is not allowed

Explanation

To give equal and opposite charges to two identical metal spheres on insulated stands without touching a charged rod to the spheres, we can use the method of charging by induction. Here’s a step-by-step solution:

### Step 1: Positioning the Spheres
- Place the two identical metal spheres close to each other so that they can come into contact with each other. Ensure that they are both on insulated stands to prevent any charge leakage.

**Hint:** The proximity of the spheres allows for charge transfer when they touch.

### Step 2: Introducing the Charged Rod
