Question

When \(10^{14}\) electrons are removed from a neutral metal sphere, the charge on the sphere becomes

• A. +32 \(\mu C\)
• B. -32 \(\mu C\)
• C. -16 \(\mu C\)
• D. +16 \(\mu C\)

Hint:

To find the charge on an object, multiply the number of electrons by the charge of one electron.

Answer 1

The Correct Option is B

The charge on one electron is \(1.6 \times 10^{-19}\) Coulombs. The total charge is: \[ \text{Charge} = 10^{14} \times 1.6 \times 10^{-19} = -32 \times 10^{-6} \, \text{C} = -32 \, \mu C \] Thus, the correct answer is \(-32 \, \mu C\).
