need help understanding what I did wrong

0 / 2 pts Incorrect Question 8 Three point charges are located on the x-axis. The first charge, q1 = 10.0 UC, is at x = -1.00 m; the second charge, q2 = 20.0 uC, is at the origin; and the third charge, q3 = -30.0 HC, is located at x = 2.00 m. Which charge is subjected to the force of greatest magnitude? O q1 q2 and q3 (equal) 93 q1 and q2 (equal)rect Question 10 0.5 / 2 pts Which of the following statements is true? If the electric field is zero throughout a region of space, then the electric potential is necessarily also zero there. The electric field is large where the potential is large, and vice versa. If the electric potential is zero at a point, then the electric field is zero at that point also. If the electric potential is zero throughout a region of space, then the electric field is necessarily also zero there. If the electric field is zero at a point, then the electric potential is zero at that point also. ncorrect Question 11 1/2 pts A 5 UC charge is moved from a position where its electric potential energy is 8 mJ to a position where its potential energy is 4 mJ. What is the change in potential from the initial position to the final position? -1,250.5 / 2 pts Incorrect Question 12 If the area of the plates of a parallel plate capacitor is tripled and the plate separation is halved, by what factor does the capacitance change? It increases by a factor of 6. O It triples. It decreases to 2/3 the original. It increases 1.5 times. It doubles
