Rub the rod vigorously with the fur for charge to it. Repeat this the outside of the can several times to transfer charge. procedure at least five times to transfer a significant rod on entire 3. Bring the aluminum covered ball hanging from the sting close to but touching the outside of the can. Question 2-4: What happens when the ball is brought close to the can? 4. Now touch the ball to the outside of the can, and then move it a very short distance away. Question 2-5: What happens after the ball is to the of the can and then moved away? Explain the difference in behavior of the ball in (3) and (4). Question what do you conclude about the presence of charge on the out side of the can? Explain based your observa ations.

Explanation / Answer

When the Aliminium ball is brought close to the out side of the can (,Let us say that Al is positievely charged). So,there will be induced opposite charge , i. e negative on the out side of the can and simultaniously positive charge on the inside of the can, When the ball touches the pail , both the charges (on the outside of can -ve and on the Al ball +ve ) will combine on the outer surface and will come to neutral. SO no charge will reside on the outer surface , but net positive charge will remain on the inner surface of the can.
