Question

A -15nC charge is located at (x, y) = (0.90cm , 0 cm).

a) What is the x-component of the electric field at the position (x, y) = (4.4cm , 0 cm)?

Express your answer to two significant figures and include the appropriate units.

b) What is the y-component of the electric field at the position (x, y) = (4.4cm , 0 cm)?

c) What is the x-component of the electric field at the position (x, y) = (?4.4cm, 0 cm)?

d) What is the y-component of the electric field at the position (x, y) = (?4.4cm, 0 cm)?

e) What is the x-component of the electric field at the position (x, y) = (0 cm, 4.4cm )?

f) What is the y-component of the electric field at the position (x, y) = (0 cm, 4.4cm )?

a) Ex = k q/r^2 = k*(-15*10^-9)/(0.035)^2 = -110204.0816 N/c, r = (4.4-0.9) = 0.035m

b)Ey = can't be calculated r = 0

c &d are same as a&b

e)Ex = can't be calculated r= 0

f) Ey = Kq/r^2 = 9*10^9*(-15*10^-9)/(0.044)^2 = 69731.40496N/c
