Rotational Motion question

2019 · 12 Jan · Shift 2 · Q48

JEE MainPhysicsRotational MotionMCQ+4 / −1
Two particles A, B are moving on two concentric circles of radii R1 and R2 with equal angular speed ω\omegaω. At t = 0, their positions and direction of motion are shown in the figure. : JEE Main 2019 (Online) 12th January Evening Slot Physics - Rotational Motion Question 176 English The relative velocity V→A−V→B{\overrightarrow V _A} - {\overrightarrow V _B}VA​−VB​ at t =π2ω{\pi \over {2\omega }}2ωπ​ is given by :
  1. A
    −ω(R1+R2) i^- \omega \left( {{R_1} + {R_2}} \right)\,\widehat i−ω(R1​+R2​)i
  2. B
    ω(R2−R1) i^\omega \left( {{R_2} - {R_1}} \right)\,\widehat iω(R2​−R1​)i
  3. C
    ω(R1+R2) i^\omega \left( {{R_1} + {R_2}} \right)\,\widehat iω(R1​+R2​)i
