ELECTRICITY : Electrostatics
What is the SI unit of electric charge?
Farad (F).
Volt (V).
Coulomb (C).
Ampere (A).
The value of Coulomb's constant (k) in SI units in a vacuum is approximately:
1.6 × 10⁻¹⁹C.
9 × 10⁻⁹N⋅m²/C².
8.85 × 10⁻¹² F/m.
9 × 10⁹ N⋅m²/C².
The process of charging a neutral object by bringing a charged object near it, without direct contact, is called:
Conduction.
Induction.
Friction.
Radiation.
If the distance between two point charges is doubled, the electrostatic force between them will be:
Halved.
Four times greater.
One-fourth of the original force.
Doubled.
The electric field lines for a positive point charge are directed:
In a circular path around the charge.
Parallel to the charge.
Away from the charge (radially outward).
Towards the charge.
