Problem

A point charge of

+6.0\,\mu\text{C}

is held stationary at the origin. Using

k=9.0\times10^{9}\,\text{N m}^2\text{C}^{-2}

, answer the following: (a) Calculate the magnitude of the electric field at the point

(0.10\,\text{m},\;0.00\,\text{m})

. (b) Find the

x

- and

y

-components of the electric field at the point

(0.10\,\text{m},\;0.10\,\text{m})

. (c) Determine the magnitude of the resultant electric field at the point given in part (b).
