Answer #1

**B)**

**E = k*q/r^2
= 9*10^9*14*10^-9/(0.014^2 + 0.059^2)**

**= 34267 N/c**

**angle made by E with +x axis**

**theta = tan^-1(5.9/1.4)**

**= 76.6 degrees**

**so, Ey = -E*sin(76.6)**

**= -34267*sin(76.6)**

**= -3.3*10^4 N/C
<<<<<<<<------------Answer**

**D) Ey = 3.3*10^4 N/C
<<<<<<<<------------Answer**

**E) E = k*q/r^2**

**= 9*10^9*14*10^-9/(0.059 - 0.014)^2**

**= 6.2*10^4 N/c (towards -x axis)**

**so, Ex = -6.2*10^4 N/c
<<<<<<<<------------Answer**

**F) Ey = 0
