    A)  48 N                     

    B)         81 N                     

    C)  24 N                     

    D)         16 N

    Correct Answer: B

    Solution :

    From Meldes law \[P\sqrt{T}=\]constant hence, \[{{P}_{1}}\sqrt{{{T}_{1}}}={{P}_{2}}\sqrt{{{T}_{2}}}\] \[6\times \sqrt{36}=4\sqrt{{{T}_{2}}}\] \[\sqrt{{{T}_{2}}}=9\]  so              \[{{T}_{2}}=81\]
