Answer:
The work done to lift the suitcase is 4 Joule.
Option B is correct.
Given:
Height = 0.5 m
Force = 8 N
To find:
Work done = ?
Formula used:
Work done is given by,
W = f × s
where f = force
s = displacement
Solution:
Work done is given by,
W = f × s
where f = force
s = displacement = height
W = 8 × 0.5
W = 4 Joule
Thus the work done to lift the suitcase is 4 Joule.
Option B is correct.
