Upload any PDF: a board paper, a previous-year JEE set, your coaching worksheet. Jigyasu pulls out every question, builds a real test from it, then reads your handwritten solutions and shows you exactly where your thinking went off track.
A 2 kg block slides down a rough incline of 30°. If μ = 0.2, find its acceleration. (g = 9.8 m/s²)
You added friction to the pull of gravity. Friction opposesthe slide, so it's mg sin θ − μmg cos θ.
You already have the papers your teachers and coaching centres hand out. Jigyasu makes every one of them worth far more than a single attempt.
Any question paper you have: board, entrance, school or coaching.
Questions, options, diagrams and marks are pulled out and organised by topic, ready to attempt.
Timed, distraction-free and exam-like, so practice feels like the day that counts.
Snap your handwritten working. We check each step and explain what you were thinking, where it broke, and how to fix it.
A red cross tells you nothing. Jigyasu reads your working line by line, finds the exact step where it went wrong, and names the misconception behind it.
You pictured friction as a force that helps the block along, so you added it to gravity's pull.
Line 4. The setup and normal force were correct; the sign of friction flipped the answer.
Draw the free-body diagram first. Mark the direction of motion, then put friction against it.
Practise this concept →When you want to revise a topic, Jigyasu fetches questions similar to the ones you missed: same concept, a harder twist, the problem run in reverse. You practise the gap, not the whole chapter again.
A 2 kg block slides down a rough incline of 30°. If μ = 0.2, find its acceleration.
A 5 kg box rests on a 37° incline with μ = 0.3. Find the minimum force needed to push it up.
At what angle does a block just begin to slide if the coefficient of static friction is 0.4?
Two blocks joined by a string slide down an incline with different μ. Find the tension in the string.
Modelled on the digital SAT. Do well in the first module and the next one gets harder; struggle, and it recalibrates to find exactly where your understanding stops. The score measures you, not just the paper.
