Sample Question 1
Electricity, Magnetism & AC CircuitsEASY • Physics (Secondary & College Level)
What is Coulomb's law for the electrostatic force between two point charges q1 and q2 separated by distance r in vacuum?
AF = (1 / (4 * pi * epsilon_0)) * (q1 * q2 / r²)
BF = (1 / (4 * pi * epsilon_0)) * (q1 * q2 / r)
CF = epsilon_0 * (q1 * q2 / r²)
DF = (q1 + q2) / r²
✓ Correct Answer:A - F = (1 / (4 * pi * epsilon_0)) * (q1 * q2 / r²)
📖 Step-by-Step Solution & Conceptual Rationale:
Coulomb's Law states force is directly proportional to the product of charges and inversely proportional to the square of distance.
Sample Question 2
Electricity, Magnetism & AC CircuitsEASY • Physics (Secondary & College Level)
What is the equivalent capacitance when two capacitors C1 and C2 are connected in parallel?
AC_eq = C1 + C2
BC_eq = (C1 * C2) / (C1 + C2)
CC_eq = 1/C1 + 1/C2
DC_eq = sqrt(C1 * C2)
✓ Correct Answer:A - C_eq = C1 + C2
📖 Step-by-Step Solution & Conceptual Rationale:
In parallel, capacitors add directly: C_eq = C1 + C2.
Sample Question 3
Electricity, Magnetism & AC CircuitsMEDIUM • Physics (Secondary & College Level)
According to Faraday's Law of Electromagnetic Induction and Lenz's Law, what is the induced electromotive force (EMF)?
AEMF = - N * (dPhi / dt)
BEMF = + N * (dPhi / dt)
CEMF = N * I * R
DEMF = B * A * t
✓ Correct Answer:A - EMF = - N * (dPhi / dt)
📖 Step-by-Step Solution & Conceptual Rationale:
Faraday-Lenz Law states induced EMF is proportional to the negative rate of change of magnetic flux through the circuit.
Sample Question 4
Electricity, Magnetism & AC CircuitsEASY • Physics (Secondary & College Level)
The rate of change of angular momentum is equal to:
AApplied Torque
BCentripetal Force
CLinear Momentum
DRotational Kinetic Energy
✓ Correct Answer:A - Applied Torque
📖 Step-by-Step Solution & Conceptual Rationale:
According to Newton's second law in rotational motion, tau = dL/dt (Torque equals rate of change of angular momentum).
