JEE Main 2026 Physics question
Match List - I with List - II. List - I: A. Boltzmann constant, B. Stefan's constant, C. Planck's constant, D. Gravitational constant. List - II: I. [M⁻¹L³T⁻²], II. [ML²T⁻¹], III. [ML²T⁻²K⁻¹], IV. [ML⁰T⁻³K⁻⁴].
Answer: (C)
Solution
=energy/temperature=ML²T⁻²K⁻¹ (III). Stefan's constant σ=power/(area·T⁴)=MT⁻³K⁻⁴ (IV). h=energy×time=ML²T⁻¹ (II). G=Fr²/m²=M⁻¹L³T⁻² (I).
