Could someone please help me with these physics questions? Please provide short explanations, I WILL RATE GOOD

7. What would the electric field lines look like if the electric field was constant? 8. Can there be a point in space where there is an electric potential but not electric field? Can there be a point in space where there is an electric field but no electric potential? Explain you answer. 9. Use Figure 5 to answer the following questions: Figure 5: Charged particles P (left) and Q (right).maps. ++++++++ + + + + + + + ++ + + + + + a. Are charges P and Q negative or positive? How do you know? b. Which particle has the highest magnitude of charge? How do you know? 10. Given the two field maps below, if the left charge (blue rectangle or circle) is positive and the right charge is negative, predict the electric field lines by drawing them over the field +++ + + + + +
