The set containing only vector quantities is

Options

A. Thermal capacity, Magnetic susceptibility and Electric charge
B. Magnetic moment, Electric intensity and Torque
C. Magnetic flux, Electric potential and Force
D. Magnetic induction, Electric capacity and Impulse

Answer

To solve the question regarding which set contains only vector quantities, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Quantities**:
- We need to determine the nature (vector or scalar) of each quantity mentioned in the options. The quantities we will analyze are:
- Magnetic moment
- Electric field intensity
- Torque

2. **Analyze Magnetic Moment**:
- The magnetic moment is defined as the measure of the strength and orientation of a magnet or current loop. It has both magnitude and direction, which makes it a vector quantity.

3. **Analyze Electric Field Intensity**:
- Electric field intensity (E) is defined as the force (F) experienced by a unit positive charge (q) placed in the field. Since force is a vector quantity and the electric field is derived from force, electric field intensity is also a vector quantity.

4. **Analyze Torque**:
- Torque (τ) is defined as the cross product of the position vector (r) and the force vector (F), given by the formula τ = r × F. The result of a cross product of two vectors is also a vector. Therefore, torque is a vector quantity.

5. **Conclusion**:
- All three quantities: magnetic moment, electric field intensity, and torque are vector quantities. Thus, the set containing these three quantities is indeed a set of vector quantities.

### Final Answer:
The set containing only vector quantities is option 2: {Magnetic moment, Electric field intensity, Torque}.
