Question

The physical quantity which has the dimensional formula $\left[M^1{T}^{-3}\right]$ is

• A. surface tension
• B. density
• C. solar constant
• D. compressibility

Answer 1

Answer: (C)

$\left[M{T}^{-3}\right]=\frac{\left[M{L}^2{T}^{-2}\right]}{\left[L^2\right][T]}$ =energy / area $\times$ time =dimension of solar constant.
