Physics MCQs
Practice Physics multiple-choice questions for UET Lahore competitive exams. Each question includes the correct answer and a short explanation, and past-paper questions are marked so you can revise both repeated and fresh material in one place.
Tangential to the path
Along the direction of velocity
Towards the center of the circle
Away from the center of the circle
ExplanationIn uniform circular motion, the acceleration is centripetal, which is always directed toward the center of the circular path.
30 ohms
15 ohms
6.67 ohms
0.15 ohms
ExplanationThe formula for parallel resistance is 1/Req = 1/R1 + 1/R2. 1/10 + 1/20 = 3/20. Therefore, Req = 20/3 = 6.67 ohms.
Zeroth Law
First Law
Second Law
Third Law
ExplanationThe Second Law of Thermodynamics dictates that the total entropy of an isolated system can never decrease.
kx
1/2 kx
1/2 kx^2
kx^2
ExplanationThe elastic potential energy in a spring is given by the integral of the restoring force, resulting in 1/2 kx squared.
Doubles
Halves
Triples
Quadruples
ExplanationKinetic energy is proportional to the square of velocity (KE = 1/2 mv^2). 2^2 = 4.
Tesla
Weber
Henry
Gauss
ExplanationThe SI unit of magnetic flux is the Weber (Wb).
Photoelectric effect
Compton scattering
Interference
Blackbody radiation
ExplanationInterference and diffraction patterns are classic proofs of the wave nature of light.
29.4 m
44.1 m
88.2 m
14.7 m
ExplanationUsing h = 1/2 gt^2, where g=9.8. h = 0.5 * 9.8 * 9 = 44.1.
Distance
Displacement
Acceleration
Jerk
ExplanationAcceleration is the rate of change of velocity, which is the slope of the v-t graph.
Double
Half
One-fourth
Four times
ExplanationAccording to Coulomb's Law, force is inversely proportional to the square of the distance (1/r^2).
MLT^-2
ML^2T^-2
ML^2T^-1
ML^-1T^-2
ExplanationWork is force times displacement (M*L*T^-2 * L = M*L^2*T^-2).
Time
Speed
Distance
Intensity
ExplanationA light year is the distance light travels in a vacuum in one Julian year.
Red
Green
Yellow
Violet
ExplanationViolet light has the shortest wavelength and thus the highest refractive index/deviation in a prism.
Electrons only
Holes only
Diffusion of charge carriers
Thermal agitation
ExplanationThe depletion region forms as electrons and holes diffuse across the junction and recombine.
9.8 m/s
11.2 km/s
3.0 x 10^8 m/s
1.6 m/s
ExplanationEscape velocity is the minimum speed needed for an object to escape the gravitational influence of a massive body.
Frequently Asked Questions
Are these Physics MCQs free?
Yes. Every Physics MCQ on this page is free to practice, including the correct answer and explanation.
Do these include past-paper questions?
Yes — questions sourced from past papers are clearly marked with a "Past Paper" badge, alongside fresh practice questions.
Which exams do these Physics MCQs help with?
They are aimed at UET Lahore and related Pakistani competitive exams that test Physics.
How should I practice subject-wise MCQs?
Attempt each question first, then reveal the answer and read the explanation. Short, focused sessions on one subject work better than long unstructured reading.
