Rotational Motion question

2021 · 25 Feb · Shift 2 · Q51

JEE MainPhysicsRotational MotionMCQ+4 / −1
A sphere of radius 'a' and mass 'm' rolls along a horizontal plane with constant speed v0. It encounters an inclined plane at angle θ\thetaθ and climbs upward. Assuming that it rolls without slipping, how far up the sphere will travel? JEE Main 2021 (Online) 25th February Evening Shift Physics - Rotational Motion Question 128 English
