Unformatted text preview: y axis is zero; the net field component along the x axis points rightward. With θ = 60 ° , E net x = 2 Q cos θ 4 πε o a 2 . Since cos(60 ° ) = 1/2, we can write this as E net = kQ/a 2 (using the notation of Eq. 21-5). Thus, E net ≈ 27 N/C. 6 3. (a) We refer to the same figure to which problem 63 refers (but without “ q ”). From...
