Practice question

L = r×p = |i^j^k^0305−20| = k^(0×(−2)−3×5) = −15k^kg m2/s. Z-component = −15kg m2/s. As per NCERT, applying relevant law/formula with correct units and sign convention leads to -15 kg m²/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
