In the system whose signal flow graph is shown in the figure, U 1 (s) and U 2 (s) are inputs. The transfer function \frac{Y (s) }{U_{1} (s) } is

Correct Answer is : k1JLs2+JRs+k1k2

{k_{1}}/{JLs^{2} + JRs + k_{1}k_{2}}

{k_{1}}/{JLs^{2}−JRs−k_{1}k_{2}}

{k_{1}−U_{2} (R + sL) }/{JLs^{2} + (JR−U_{2}L) s + k_{1}k_{2}−U_{2}R}

{k_{1}−U_{2} (sL−R) }/{JLs^{2}− (JR + U_{2}L) s−k_{1}k_{2} + U_{2}R}
