In differential amplifier the input are given as V1=30sinΠ(50t)+10sinΠ(25t) , V2=30sinΠ(50t)-10 sinΠ(25t), β0 =200,RE =1kΩ and RC = 15kΩ. Find the output voltages V01, V02 & gm=4MΩ^-1

(a) V01=-60[10 sinΠ(25t) ]-6.637[30sinΠ(50t) ], V02=60[10 sinΠ(25t) ]-6.637[30sinΠ(50t) ].

(b) V01=-6.637[10 sinΠ(25t) ]-60[30sinΠ(50t) ], V02=6.637[10 sinΠ(25t) ]-60[30sinΠ(50t) ].

(c) V01=-60[30 sinΠ(50t) ]-6.637[10sinΠ(25t) ], V02=60[30 sinΠ(50t) ]-6.637[10sinΠ(25t) ].

(d) V01=-6.637[30 sinΠ(50t) ]-60[10sinΠ(25t) ], V02=6.637[30 sinΠ(50t) ]-60[10sinΠ(25t) ].

I had been asked this question in a national level competition.

This interesting question is from Operational Amplifier Internal Circuit topic in chapter Operational Amplifier of Linear Integrated Circuits
