If a charged body is placed near a neutral conductor, will it attract the conductor or repel it ?

Text Solution

Verified by Experts


If a charged body (+ve) is placed leftside near a neutral conductor, (-ve) charge will induce at left surface and (+ve) charge will induce at right surface. Due to positively charged body +ve induced charge will feel attraction and the +ve induced charge will feel repulsion. But as the -ve induced charge is nearer, so the attractive force will be greater than the repulsive force. So the net force on the conductor due to positively charged body will be attractive. Similarly we can prove for negatively charged body also.
From the above example we can conclude that ''A charged body can attract a neutral body".
If there is attraction between two bodies then one of them may be neutral. But if there is repulsion between two bodies, both must be charged (similarly charged)
So "repulsion is the sure test of electrification".
