Question

When 10¹⁴ electrons are removed from a neutral metal sphere, the charge on the sphere becomes ______.

Answer 1

When 10¹⁴ electrons are removed from a neutral metal sphere, the charge on the sphere becomes 16 µC.

Explanation:

Q = ne

Q = 10¹⁴ × 1.6 × 10⁻¹⁹

Q = 1.6 × 10⁻⁵ C

And since

1 μC = 10⁻⁶ C,

1.6 × 10⁻⁵ C = 16 × 10⁻⁶ C = 16 μC.

So the magnitude is 16 μC.
