If $F_1$ and $F_2$ are the relative strengths of the gravitational and weak nuclear forces respectively, then $\frac{F_2}{F_1}$ is nearly

If $F_1, F_2$, and $F_3$ are the relative strengths of the gravitational, the weak nuclear, and the electromagnetic forces respectively, then

In the following list,the only pair which has different dimensions is

To determine the Young's modulus of a wire,the formula is $Y = \frac{FL}{A\Delta L}$,where $L$ is the length,$A$ is the area of cross-section of the wire,and $\Delta L$ is the change in length of the wire when stretched with a force $F$. The conversion factor to change the unit of Young's modulus from $CGS$ to $MKS$ system is $x \times 10^{-1} \ N/m^2$. Find the value of $x$.

Match List-$I$ with List-$II$:

List-$I$	List-$II$
$(A)$ Torque	$(I)$ $ML^{-2}T^{-2}$
$(B)$ Stress	$(II)$ $ML^2T^{-2}$
$(C)$ Pressure gradient	$(III)$ $ML^{-1}T^{-1}$
$(D)$ Coefficient of viscosity	$(IV)$ $ML^{-1}T^{-2}$
