,1. Multiple Choice: What is the SI unit of electric charge?
a) Ampere
b) Coulomb
c) Ohm
d) Volt
Correct Answer: b) Coulomb
Rationale: The Coulomb is the standard SI unit for measuring
electric charge, named after Charles-Augustin de Coulomb.


2. Fill-in-the-Blank: The electric field strength at a point in space is
defined as the _______ per unit charge.
Correct Answer: Force
Rationale: Electric field strength is the force experienced by a
unit positive charge placed at that point.


3. True/False: The magnetic field lines inside a solenoid are
parallel to each other.
Correct Answer: True
Rationale: Inside a solenoid, the magnetic field lines are indeed
parallel, indicating a uniform magnetic field.

, 4. Multiple Response: Which of the following are vector
quantities? (Select all that apply)
a) Electric potential
b) Magnetic field
c) Electric field
d) Electric current
Correct Answers: b) Magnetic field, c) Electric field
Rationale: Both magnetic and electric fields are vector quantities
because they have both magnitude and direction.


5. Multiple Choice: Faraday's Law of Electromagnetic Induction
states that the induced electromotive force in any closed circuit is
equal to the negative of the time rate of change of the _______
through the circuit.
a) Electric field
b) Magnetic flux
c) Resistance
d) Current
Correct Answer: b) Magnetic flux
Rationale: Faraday's Law relates the induced electromotive force
to the change in magnetic flux.
