Question

Two particles move on the same circular path with equal speed but are at different positions. Which statements are correct?

G1 Physics · Accepted Answer

Equal speeds imply equal velocity magnitudes. Since the particles are at different positions, their tangent directions can differ, so velocity vectors need not be equal. Because a_c=v²/R, radial acceleration magnitudes are equal, but the inward directions toward the centre are generally different, so the vectors may differ.
