Chapter 6: Problem 12

An uncharged body ' \(\mathrm{X}\) ' is brought into contact with a negatively charged body 'Y', then, (1) 'X' gains negative charge. (2) 'Y' loses negative charge. (3) negative charge gained by ' \(\mathrm{X}\) ' is equal to the negative charge lost by ' \(\mathrm{Y}\) '. (4) All the above

Short Answer

Expert verified

1. 'X' gains negative charge. 2. 'Y' loses negative charge. 3. Negative charge gained by 'X' is equal to the negative charge lost by 'Y'. 4. All the above. Answer: 4. All the above.

Step by step solution

Statement 1: 'X' gains negative charge.

When an uncharged body comes into contact with a charged body, the uncharged body will gain some charge from the charged body. This happens because the charges redistribute themselves to achieve equilibrium. In this case, since 'Y' is negatively charged, 'X' will gain negative charge.

Statement 2: 'Y' loses negative charge.

As mentioned earlier, when the two bodies are brought into contact, the charges redistribute to achieve equilibrium. Since 'X' gains some of the negative charge from 'Y', it means 'Y' loses some of its negative charge in the process.

Statement 3: Negative charge gained by 'X' is equal to the negative charge lost by 'Y'.

When the charges redistribute between the two bodies, their total charge is conserved. So, whatever amount of negative charge 'X' gains, 'Y' will be losing an equal amount of charge to maintain the total charge in the system.

Statement 4: All the above.

As we analyzed each statement, we found that all of them are true. 'X' gains negative charge, 'Y' loses negative charge, and the amount of charge gained by 'X' is equal to the amount lost by 'Y'. Therefore, the correct answer is (4) All the above statements are true.
