Identical $\backslash (45\backslash$mu $\backslash$mathrm$\{$C$\}\backslash )$ charges are fixed on an $\backslash ($ x $\backslash )$ axis at $\backslash ($ x$=\backslash$pm $2\mathrm{.}6\backslash$mathrm$\{$~m$\}\backslash ).$ A particle of charge $\backslash ($ q$=-17\backslash$mu $\backslash$mathrm$\{$C$\}\backslash )$ is then released from rest at a point on the positive part of the $\backslash ($ y $\backslash )$ axis. Due to the symmetry of the situation, the particle moves along the $\backslash ($ y $\backslash )$ axis and has kinetic energy $1\mathrm{.}1$ J as it passes through the point $\backslash ($ x$=0,$ y$=4\mathrm{.}5\backslash$mathrm$\{$~m$\}\backslash ).($a$)$ What is the kinetic energy of the particle as it passes through the origin? $($b$)$ At what negative value of $\backslash ($ y $\backslash )$ will the particle momentarily stop?
