If the depth d to which a bullet of kinetic energy K can penetrate into a human body of modulus of electicity E, using the method of dimension, establish a relation between d, K and E . If `K=cd^(x) E^(y)`, fill x+y in OMR sheet. Modulus of elasticity =Force/Area ,`xx l/(Deltal)` |

Answer» Correct Answer - `0004` `K=cd^(x) E^(y)` `ML^(2)T^(-2)=L^(X)[ML^(-1)T^(-2)]^(Y)` `-2=-2y " " rArr y=1` `2=x-y " " rArr x=3 " " x+y=4` |
