What are the strength and direction of the electric field at the position indicated by the dot in FIGUREEX23.3?Specify the direction as an angle above or below horizontal.

Short Answer

Expert verified

The strength of the electric field is 7.63×103V/m.

Step by step solution

01

Angle of electric field diagram

Figure is,

02

Calculation for magnitude of E1

The electric field's magnitude is,

E=E2cosθ-E1cosθi-E2sinθ+E1sinθj

E1:

E1=KQ1AB2

E1=9×109N3.0×10-9C(52cm)2

E1=5.4×103V/m

03

Calculation for magnitude of E2

E2:

E2=KQ2BC2

E2=9×109N3.0×10-9C(52cm)2

E2=5.4×103V/m

ΔABC,sinθ=cosθ=12

So,

localid="1649136637521" E=E2cosθ-E1cosθi-E2sinθ+E1sinθj

E=(0)i-2×5.4×103V/m×12j

E=7.63×103V/mj
