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)|)))#
