Question

Two particles A , B are moving on two concentric circles of radii R 1 and R 2 with equal angular speed ω . At t = 0 , their positions and direction of motion are shown in the figure: The relative velocity V A → - V B → at t = π 2 ω is given by:

TestHub · Accepted Answer

t = π 2 ω V → A = ω R 1 - i ^ V → B = ω R 2 - i ^ V A → - V B → = ω R 2 - R 1 i ^
