$($a$)$What are the x and y components of the electric filed at the origin O due to charge q$1?(4$pt$)$

$($b$)$What are the x and y components of the electric filed at the origin due to q$2?(4$pt$)$

$($c$)$What are the x and y components of the electric filed at the origin due to q$3?(4$pt$)$

$($d$)$What are the x and y components of the net electric filed at the origin from all three charges? What are its magnitude and direction? $(4$pt$)$

$($e$)$What are the x and y components of an electron$$s acceleration at the origin? $(4$pt$)$

Bonus: A fourth charge is placed at $($x$,$ y$)=(4$a$,0).$ What should be its value to ensure that the x$-$component of the new net electric field at the origin is zero $(3$pt$)$
