Electric field for a point charge:
For multiple charges:
Enet x = E1x + E2x = E1cosθ1 + E2cosθ2
Two point charges (q1 = -4.7 µC and q2 = 8.4 µC) are fixed along the x-axis, separated by a distance d = 8.1 cm. Point P is located at (x,y) = (d,d).
1) What is Ex(P), the value of the x-component of the electric field produced by q1 and q2 at point P?
2) What is Ey(P), the value of the y-component of the electric field produced by q1 and q2 at point P?
