Electric field of a system of charges does not depend on

Options

A. position of charges forming the system
B. distance of point (at which field is being observed) from the charges forming system
C. value of test charge used to find out the field
D. separation of charges forming the system

Answer

To solve the question regarding the electric field of a system of charges and what it does not depend on, we can break down the problem step by step.

### Step-by-Step Solution:

1. **Understanding Electric Field**:
The electric field (E) created by a point charge (Q) at a distance (r) from the charge is given by the formula:
\[ E = \frac{1}{4\pi\epsilon_0} \cdot \frac{Q}{r^2} \]
Here, \( \epsilon_0 \) is the permittivity of free space.

2. **Identifying Dependencies**:
From the formula, we can see that the electric field depends on:
- The magnitude of the charge (Q).
- The distance (r) from the charge.

3. **Test Charge**:
The electric field is defined independently of the test charge used to measure it. The test charge (q₀) is used to determine the force experienced by it in the electric field but does not influence the electric field itself. Thus, the electric field does not depend on the value of the test charge.

4. **Separation of Charges**:
The electric field also depends on the configuration of the charges in the system. If the charges are separated by a distance, the electric field will change based on that separation.

5. **Conclusion**:
Based on the analysis, the electric field does not depend on the value of the test charge used to find it. Therefore, the correct answer to the question is that the electric field does not depend on the value of the test charge.

### Final Answer:
The electric field of a system of charges does not depend on the value of the test charge used to measure it.
