Express your answers using two significant figures. Enter your answers numerically separated by a comma.
Part C
What is the electric field at the position (x3,y3)=(5.0cm,5.0cm)? Write electric field vector in component form.
Express your answers using two significant figures. Enter your answers numerically separated by a comma.
E2x, E2y = N/CExplanation / 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)

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
