Let's analyze the electric field due to charge Q based on the description you've provided:
-
Charge Q is positive: This statement is correct. If the electric field vectors are radially outward from charge Q, then Q is a positive charge. Electric field lines point away from positive charges.
-
Charge Q is negative: This statement is incorrect. As established above, since the field lines are pointing outward, Q is a positive charge.
-
The electric field is uniform: This statement is incorrect. Electric fields from point charges are not uniform; they vary with distance from the charge. In this case, the field strength decreases as you move away from charge Q.
-
The electric field is nonuniform: This statement is correct. The electric field decreases in strength with increasing distance from the charge, indicating that it is nonuniform.
-
If charge A is negative, it moves away from charge Q: This statement is incorrect. A negative charge experiences an attractive force towards the positive charge, hence charge A would move towards charge Q.
-
If charge A is positive, it moves away from charge Q: This statement is correct. A positive charge experiences a repulsive force when near another positive charge, so charge A would indeed move away from charge Q.
In summary, the correct statements are:
- Charge Q is positive.
- The electric field is nonuniform.
- If charge A is positive, it moves away from charge Q.
