Question

A 3kg mass rotates in a circle of radius 0.6m with a speed of 4m/s. What is its angular momentum about the center?

Options

Choose one · Correct answer highlighted

Explanation

L = mvr. m = 3kg, v = 4m/s, r = 0.6m. L = 3×4×0.6 = 7.2kg m2/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 7.2 kg m²/s. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
