Two point charges are placed at the two corners of a triangle as shown In Figure 1. The charges are \( q_{1}=+10 \mu \mathrm{C} \), and \( q_{2}=-10 \mu \mathrm{C} \).
Figure 1
i) Draw a vector diagram and show the electric field vectors \( E_{1} \) and \( E_{2} \) at point \( X \) due to charge \( q_{1} \) and \( q_{2} \) respectively.
(1 mark)
i) Calculate the magnitude and direction of the resullant electric fieid at point \( X \).
