    In Ingen hausz experiment the wax melts upto 2 cm and 5 cm on the iron and the silver rods respectively. If K for silver is taken as 1, then its value for iron is

    A)  0.4                                        

    B)  0.16

    C)  2.5                                        

    D)  6.25

    Correct Answer: B

    Solution :

                     In Ingen Hausz experiment \[K\propto {{l}^{2}}\] \[\therefore \]  \[\frac{{{K}_{Fe}}}{{{K}_{Ag}}}={{\left( \frac{{{l}_{Fe}}}{{{l}_{Ag}}} \right)}^{2}}\]                 \[\frac{{{K}_{Fe}}}{1}={{\left( \frac{2}{5} \right)}^{2}}\]                 \[{{K}_{Fe}}=\frac{4}{25}\]                 \[=0.16\]
