What is the story about?
JEE Main 2026 session 1 exams are scheduled to begin on January 21 (Wednesday). It's less than a week before the examinations begin, and all engineering
college aspirants are busy solving sample papers and previous year question papers to prepare for the first session of the examination. To help you with your quick prep, we bring you 10 questions (combined from Physics, Chemistry and Mathematics) which are concept based, and are based on the questions that appeared in the 2024 session 2 exam paper. Get solving, and see if you ready to crack one of the toughest exams of the world.
Physics (Conceptual)
A satellite moves around the Earth in a circular orbit with constant speed. Which statement is correct about its acceleration?
A) Zero
B) Along the direction of motion
C) Towards the centre of the Earth
D) Opposite to velocity
Two bodies of different masses are dropped from the same height in vacuum. Which reaches the ground first and why?
When a ray of light enters from air into glass, which of the following remains unchanged?
A) Speed
B) Wavelength
C) Frequency
D) Direction
A magnet is dropped through a copper tube. It falls slower than in air. The reason is:
A) Air resistance
B) Magnetic attraction
C) Eddy currents
D) Change in gravity
Chemistry (Conceptual / NCERT-based)
Which of the following shows maximum hydrogen bonding?
A) H₂O
B) H₂S
C) NH₃
D) PH₃
Why does fluorine not show positive oxidation states, unlike other halogens?
Among the following, which compound has the highest boiling point and why?
A) Methane
B) Ethane
C) Propane
D) Butane
Which orbital has the highest penetration towards the nucleus?
A) 2s
B) 2p
C) 3s
D) 3p
Mathematics (Logic / Visual / Property-based)
If all roots of a quadratic equation are real and equal, what can be said about the graph of the equation?
A) It cuts the x-axis at two points
B) It touches the x-axis at one point
C) It never touches the x-axis
D) It is a straight line
A function is symmetric about the y-axis. Which statement must be true?
A) f(x) = –f(x)
B) f(x) = f(–x)
C) f(x) = x
D) f(x) = constant
Answer Key
| Q. No. | Correct Answer |
|---|---|
| 1 | C |
| 2 | Both reach at the same time (because acceleration due to gravity is same in vacuum) |
| 3 | C |
| 4 | C |
| 5 | A |
| 6 | Because fluorine is the most electronegative element and has no d-orbitals |
| 7 | D |
| 8 | A |
| 9 | B |
| 10 | B |
