Question

Metal sphere having an excess of +5 elementary charges has a net electric charge of

Answer 1

Answer:

$q=+8.01\cdot 10^{-19}\ coulombs$

Explanation:

Elementary charge

The elementary charge, denoted by the symbol e is the electric charge carried by a proton or, equivalently, the magnitude of a negative electric charge carried by an electron, which has charge −e.

The value of the elementary charge is a fundamental constant in physics:

$\mathbf{e}=1.60217662 \cdot 10^{-19}\ coulombs$

If a metal sphere has an excess of +5 elementary charge, then it has a net charge of:

$q=5*\mathbf{e}=+5*1.60217662 \cdot 10^{-19}\ coulombs$

$\boxed{q=+8.01\cdot 10^{-19}\ coulombs}$
