scenario here: whenever you will select category as hardware then assignment group will set hardware.

Note: you can try with that and made some changes according to your requirement. 

sample script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

//Type appropriate comment here, and begin script below
var ct = g_form.getValue('category');
if(ct == 'hardware' )
{
g_form.setValue('assignment_group','8a5055c9c61122780043563ef53438e3'); //sysid of group . i just added hardware group sysid
}

}
