Question
In the differential amplifier shown below, find:

(a) The differential mode gain  
(b) The common mode gain  
(c) The CMRR (Common Mode Rejection Ratio)

**Circuit Details:**

- **Inputs:** Two voltage sources \( V_a \) and \( V_b \)
- **Resistors:**
  - \( R_1 = 5 \, \text{k}\Omega \)
  - \( R_2 = 5 \, \text{k}\Omega \)
  - \( R_3 = 95 \, \text{k}\Omega \)
  - \( R_4 = 100 \, \text{k}\Omega \)
  
- **Operational Amplifier:** 
  - Non-inverting input connected to \( V_b \) through \( R_2 \), and inverting input connected to \( V_a \) through \( R_1 \)
  - Feedback resistor \( R_4 \) connected between the output and the inverting input
  - \( R_3 \) connected between the inverting input and ground
  - Output voltage \( V_o \)

**Output Characteristics:**
- **Voltage Supply Limits:** \( +10 \, \text{V} \) and \( -10 \, \text{V} \)
- The output \( V_o \) is measured across the operational amplifier with reference to ground.
