Question

Two point charges (q1 = -4?C and q2 = 8 ?C) are fixed along the x-axis, separated by a distance d = 9.9 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?N/C

3)

A third point charge q3 = 2.5 ?C is now positioned along the y-axis at a distance d = 9.9 cm from q1 as shown. What is Ex(P), the x-component of the field produced by all 3 charges at point P?

N/C 1298635.043

please help its due in 3 hours and I tried using the rules and kept getting wrong numbers !

Explanation / Answer

there will not be any x componenet due to q2

becaue it is directly below th point P

Electric field due to q1 at point P E=kq1/2d2

x component of that field=Esin45
