....... Is an electric device that use for storing charges

• A conductor

• B insulator

• C capacitor

• D resistor

Columns law states that

• A: F=kq1q2/r²

• B:F=Gq1q2/r²

• C:F=kq1q2/r

• D:F=k q1+q2/r²

Answer explanation

The columns law states that the force of attraction between two particles of charges is directly proportional to the charges and inversely proportional to the square distance between them which is F= kq1q2/r²

The region or space where electrical charges can be experience is called

• A: magnetic field

• B: magnetic flux

• C: electrical flux

• D: electric field
