Express your answers using two significant figures. Enter your answers numerically separated by a comma.

E2x, E2y =   N/C  

Explanation / Answer

B)
E2x will be in negative x direction
E2x = -K*q / x^2
= -(9*10^9)*(11*10^-9) / (0.05)^2 {x = 5cm = 0.05 m}
= -39600 N/C

E2y will be in positive y direction
E2y = K*q / y^2
= (9*10^9)*(11*10^-9) / (0.05)^2 {x = ycm = 0.05 m}
= 39600 N/C

Answer: -39600 N/C , 39600 N/C

C)
E2x will be in negative x direction
E2x = -K*q / x^2
= -(9*10^9)*(11*10^-9) / (0.05)^2 {x = 5cm = 0.05 m}
= -39600 N/C

E2y will be in negative y direction
E2y = -K*q / y^2
= -(9*10^9)*(11*10^-9) / (0.05)^2 {x = ycm = 0.05 m}
= -39600 N/C

Answer: -39600 N/C , -39600 N/C
