A positively charged glass rod is brought near uncharged metal sphere, which is mounted on an insulated stand. If the glass rod is removed, the net charge on the metal sphere is
- Zero
- 1.6 × 10-19 C
- Positive Charge
- Negative Charge
The Correct Option is A
Solution and Explanation
Given:
- A positively charged glass rod is brought near an uncharged metal sphere.
- The sphere is mounted on an insulated stand.
- The glass rod is then removed.
Step 1: Understanding Electrostatic Induction
When a charged object (glass rod) is brought near a conductor (metal sphere), it induces charge separation. The negative charges in the metal sphere move towards the glass rod, while the positive charges move away.
Step 2: What Happens When the Glass Rod is Removed?
Since the metal sphere is not grounded and no charge transfer has occurred, the charge redistribution disappears after removing the glass rod. The net charge on the sphere remains zero.
Answer: The correct option is A (Zero).
