The force #F=2/3 k_e#
where #k_e=8.99" x "10^9" " "Newton" * "meter"^2*"Coulomb"^(-2)#

The formula for the force

#F=k_e abs(q_1 q_2)/r^2#

where #k_e=8.99" x "10^9" " "Newton" * "meter"^2*"Coulomb"^(-2)#

#F=k_e abs(q_1 q_2)/r^2#

#F=k_e abs((-6)(-9))/(9^2)#

#F=2/3k_e#

The actual numerical value #F=5.99333# x #10^9# Newtons

God bless....I hope the explanation is useful.
