Could i please get some assistance on this, thank you.

Question 1 . U + + + + + + + + + 8.30 nC of charge is uniformly distributed along a thin rod of length L = 5.70 cm as shown in the figure. What is the magnitude of the electric field at point P, a distance r= 16.0 cm from the centre of the rod? Magnitude:Question 2 Two thin rods of length 66.0 cm are placed side-by-side as shown below, separated by a distance x: 3.70 cm. The positive rod has total charge 5.60 ml. The electric eld a distance d: 16.2 cm away from the positive rod is zero. What is the magnitude of the charge on the negative rod
