For rolling without slipping: v = ωr. v = 5m/s, r = 0.1m. ω = vr = 50.1 = 50rad/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 50 rad/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.

v = ωr. ω = 10rad/s, r = 0.3m. v = 10×0.3 = 3m/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 3.0 m/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
