Explanation:
The equation for the force of gravity acting on a stationary object at or near the surface of the earth is given by:
#F_G=mg#
We have the following information:
#|->m=20" kg"# #|->g=9.81" m"//"s"^2#
Therefore:
#F_G=(20" kg")(9.81" m"//"s"^2)#
#=196.2" N"#
#~~color(darkblue)(196" N")# (downward)
