MCQ

If an object is positively charged, theoretically the mass of the object ______?

A
Increases slightly by a factor of $9.11 \times 10^{-31} kg$.
✓
Decreases slightly by a factor of $9.11 \times 10^{-31} kg$.
C
Remains the same.
D
May increase or decrease.

✓

Answer

Correct option: B.

Decreases slightly by a factor of $9.11 \times 10^{-31} kg$.

b. Decreases slightly by a factor of $9.11 \times 10^{-31} kg$.
Explanation:
If an object is positively charged it loses some of its electrons. The mass of an electron is $9.11 \times 10^{-31} kg$. So, if a positively charged body loses $' n '$ number of electrons, it mass decrease by the amount $n \times 9.11 E ^{-31} kg$.
