The positions of \( Q_{1} \) and \( Q_{2} \) are fixed as shown. One grid unit is 0.01 m .
Angles are measured anti-clockwise from the positive \( x \) (horizontal) axis.
Use \( k=9 \times 10^{9} \frac{\mathrm{~N} \mathrm{~m}^{2}}{\mathrm{C}^{2}} \) for calculations.
What are the x and y components of the electric field at point A ?
(a) \( E_{x}=-33 \mathrm{MN} / \mathrm{C} \), and \( E_{y}=25.7 \mathrm{MN} / \mathrm{C} \)
(b) \( E_{x}=-33 \mathrm{MN} / \mathrm{C} \), and \( E_{y}=-25.7 \mathrm{MN} / \mathrm{C} \)
(c) \( E_{x}=33 \mathrm{MN} / \mathrm{C} \), and \( E_{y}=25.7 \mathrm{MN} / \mathrm{C} \)
(d) \( E_{x}=33 \mathrm{MN} / \mathrm{C} \), and \( E_{y}=-25.7 \mathrm{MN} / \mathrm{C} \)
(e) \( E_{x}=0 \mathrm{~N} / \mathrm{C} \), and \( E_{y}=25.7 \mathrm{MN} / \mathrm{C} \)
