Options

A. Magnetic field only
B. Electric field only
C. Both electric and magnetic fields
D. No electric and magnetic fields

Explanation

To solve the question regarding the region surrounding a stationary electric dipole, we can break it down into the following steps:

### Step 1: Understanding the Electric Dipole
An electric dipole consists of two equal and opposite charges, typically represented as +q (positive charge) and -q (negative charge), separated by a small distance 'd'. The dipole moment (p) is defined as p = q * d, pointing from the negative charge to the positive charge.

**Hint:** Remember that an electric dipole is characterized by two charges of equal magnitude but opposite signs.

### Step 2: Analyzing the Stationary Condition
The problem specifies that the dipole is stationary. This means that both charges are at rest and not moving. The key point here is that only moving charges create a magnetic field.

**Hint:** Recall that magnetic fields are generated by moving charges or current. Since the dipole is stationary, it does not produce a magnetic field.

### Step 3: Electric Field Generation
Even though the dipole is stationary, it still generates an electric field around it due to the presence of the positive and negative charges. The electric field lines emanate from the positive charge and terminate at the negative charge.

**Hint:** Visualize the electric field lines: they start from the positive charge and end at the negative charge, indicating the direction of the electric field.

### Step 4: Conclusion on Fields Present
Since the stationary dipole does not produce a magnetic field, but does produce an electric field, we can conclude that in the region surrounding a stationary electric dipole, there exists an electric field but no magnetic field.

**Hint:** Summarize the findings: stationary dipoles produce electric fields but do not produce magnetic fields.

### Final Answer
In conclusion, the region surrounding a stationary electric dipole has an electric field but no magnetic field.
