shelf a distance of 0.6 m above the counter?
(g=9.8m/s)

49.98 N-m

Explanation:

Weight of the bag=8.5 kg

distance = 0.6 m

            g =g=9.8m/s

we know that

                   W= F*d

                 F= mg

                    = 8.5*9.8 = 83.5 N

                 W = 83.5* 0.6

                       =49.98 N-m
