#8.17xx10^-10N#

Explanation:

The gravitational force can be calculated with the formula:

#color(blue)(|bar(ul(color(white)(a/a)F_g=(Gm_1m_2)/R^2color(white)(a/a)|)))#

where:
#F_g=#gravitational force
#G=#gravitational constant
#m_1=#mass of object #1#
#m_2=#mass of object #2#
#R=#distance from object #1#'s centre to object #2#'s centre

Substitute your known values into the formula to determine the gravitational force.

#F_g=(GMm)/R^2#

#F_g=((6.67xx10^-11(N*m^2)/(kg^2))(7.00kg)(7.00kg))/(2.00m)^2#

#F_g~~color(green)(|bar(ul(color(white)(a/a)8.17xx10^-10Ncolor(white)(a/a)|)))#
