Question

A metal sphere has a charge of +12C. What is the net charge after 5.9 x 1013 electrons have been placed on it?

Answer 1

Step-by-step explanation:

Given

Charge on metal sphere
`Q=12\mu C`

no of electrons
`n=5.9* 10^(13)`

Charge on each electron
`q=-1.6* 10^(19)\ mu C`

Charge by Possessed by Electrons
`Q_2=-1.6* 10^(19)* 5.9* 10^(13)`

`Q_2=-9.44\mu C`

Net Charge on Sphere
`Q_(net)=Q+Q_2`

`Q_(net)=12-9.44=2.56\mu C`
