Unformatted text preview: x axis is zero; the net field component along the y axis points upward. With θ = 60 ° , net, 2 sin 2 4 y Q E a = . Since sin(60 ° ) = 3 /2 , we can write this as E net = kQ 3 /a 2 (using the notation of the constant k defined in Eq. 21-5). Numerically, this gives roughly 47 N/C....
