Answer:
The <em>correct</em> statements are:
- <em>A. The electric field is nonuniform.</em>
- <em>D. Charge Q is positive.</em>
- <em>E. If charge A moves toward charge Q, it must be a negative charge</em>
Explanation:
The answer choices are:
- A. The electric field is nonuniform.
- B. The electric field is uniform.
- C. Charge Q is negative.
- D. Charge Q is positive.
- E. If charge A moves toward charge Q, it must be a negative charge.
- F. If charge A moves toward charge Q, it must be a positive charge.
The <em>electric field</em> is the electrostatic force per unit of charge,
around around a charge, where another charge would experience the electrostatic force.
The electric field lines are shown in a diagram with arrows ditributed radially away from a positive charge and radially toward a negative charge.
Since the arrows are away from Q, Q is a positive charge: <em>statement D.</em>
Since the size of the arrows decreases as you move away from Q the stregth of the field is not uniform: <em>statement A.</em>
Since the charge Q is positive, a negative charge would be attracted toward it: <em>statement E.</em>
