Why do materials like steel require a significantly larger force to produce small deformations compared to materials lik
Steel has a much larger Young’s modulus compared to rubber, meaning it has greater stiffness and requires more force to produce the same strain. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Due to larger Young’s modulus. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
