JEE Main 2024 Physics question
A solid sphere and a hollow cylinder roll up without slipping on same inclined plane with same initial speed v. The sphere and the cylinder reaches upto maximum heights and , respectively, above the initial level. The ratio is . The value of n is .
Answer: 7
Solution
h = (v²/2g)(1 + k²/R²): sphere 7/5, hollow cylinder 2, so h₁ : h₂ = 7/10.
