Answer:

#0.98J#

Explanation:

#"Work (J)" = "Force (N)" xx "Distance (m)"# or
#W = FxxD#

The force is #9.8N#
The distance is #10cm#
The distance in metres is #"10cm" /100 = 0.1m#

#W = 9.8Nxx0.1m = 0.98J#

Always be sure that you use the correct units. In this case, Newtons for the force and metres for the distance
