$(10\%)$ Problem $10$: A charge of $q=7\mathrm{.}1{10}^{-16}C$ is placed in a constant electric field of $E=4\mathrm{.}3i\frac{N}{C}.$

The charge is located at a distance $r=15cm$ from the origin at angle $=15$ above the $x-$axis.$\frac{?}{{?}_{\frac{?}{?}}33}\%$ Part $($a$)$ Write an expression for the force, $F_x,$ that the charge experiences in the x$-$direction, in terms of the charge $q$ and magnitude of the electric field $|E|.F_x=33\%$ Part $($c$)$ What is the magnitude of the force vector, $|F|$ in N$?$

$|F|=,$
