  • question_answer Dimensions of pressure are same as that of                 [CBSE PMT 1995]

    A)                 Energy   

    B)                 Force

    C)                 Energy per unit volume       

    D)                 Force per unit volume

    Correct Answer: C

    Solution :

               Pressure \[=\frac{\text{Force}}{\text{Area}}\]\[=\frac{[ML{{T}^{-2}}]}{[{{L}^{2}}]}=[M{{L}^{-1}}{{T}^{-2}}]\] Energy per unit volume \[=\frac{[M{{L}^{2}}{{T}^{-2}}]}{[{{L}^{3}}]}=[M{{L}^{-1}}{{T}^{-2}}]\]
