Question

A particle rotates about a fixed axis at a radius of 0.3m with a linear speed of 6m/s. What is its angular velocity?

Options

Choose one · Correct answer highlighted

Explanation

v = ωr. v = 6m/s, r = 0.3m. ω = vr = 60.3 = 20rad/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 20 rad/s. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
