Question

A particle moves in a circle of radius 0.5m with an angular velocity of 4rad/s. What is the magnitude of its linear velocity?

Options

Choose one · Correct answer highlighted

Explanation

Linear velocity: v = ωr. ω = 4rad/s, r = 0.5m. v = 4×0.5 = 2m/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 2 m/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
