#26.86\ N \quad (\text{downward})#

Gravitational force on the object

#=mg=6\times9.81=58.86 \ N#

Spring force on the object

#=kx=4\times 8=32 \ N#

Net force on the object

#=\text{downward gravitational force on mass }-\text{upward spring force }#

#=58.86-32#

#=26.86\ N \quad (\text{downward})#
