Friction & Inclined Planes — Previous-Year Questions
5 previous-year questions on Friction & Inclined Planes, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question carries a worked-out explanation.
Q1. A block of mass 2 kg is on a rough incline (μ = 0.5, θ = 30°). The friction force is:
JEE 2019Q2. The angle of repose for a body on an inclined plane is 30°. The coefficient of static friction is:
JEE 2020Q3. A body slides down an incline of 45° with acceleration g/2√2. The coefficient of kinetic friction is:
JEE 2018Q4. A 10 kg block is pushed against a wall with force F. If μₛ = 0.4, minimum F to prevent sliding is:
JEE 2021Q5. Two blocks A (2kg) and B (4kg) are on a surface with μ = 0.2. A force F is applied on A. Max F so both move together:
