Question

Dimensions of Stefan’s constant is:

• A. \( [ML^{-1}T^{-3}\theta^{-4}] \)
• B. \( [MT^{-3}\theta^{-4}] \)
• C. \( [M^2T^{-3}\theta^{-4}] \)
• D. \( [M^2T^{-2}\theta^{-4}] \)

Hint:

Stefan constant = power per unit area per \(T^4\), so no length term remains.

Answer 1

The Correct Option is B
