JEE Main 2019 — Motion In Two Dimensions Question with Solution

JEE Main 2019 (12 Jan Shift 2)

Question

Two particles A, B are moving on two concentric circles of radii R1 and R2 with equal angular speed ω. At t=0, their positions and direction of motion are shown in the figure:

The relative velocity VA→-VB→ at t=π2ω is given by:

Correct answer
DωR2-R1i^

Step-by-step explanation

t=π2ω

V→A=ωR1-i^

V→B=ωR2-i^

VA→-VB→=ωR2-R1i^
