Rotational Motion question

2023 · 13 Apr · Shift 1 · Q54

JEE MainPhysicsRotational MotionMCQ+4 / −1
A disc is rolling without slipping on a surface. The radius of the disc is RRR. At t=0t=0t=0, the top most point on the disc is A\mathrm{A}A as shown in figure. When the disc completes half of its rotation, the displacement of point A from its initial position is JEE Main 2023 (Online) 13th April Morning Shift Physics - Rotational Motion Question 57 English
