A cantilever beam $\text{'}A\text{'}$ with rectangular cross section is subjected to a concentrated load at its free end. If width and depth

of another cantilever beam $\text{'}B\text{'}$ are twice those of beam $A,$ then the deflection at free end of the beam $\text{'}B\text{'}$ as compared to

that of $\text{'}A\text{'}$ will be
