Answer:
Work done, W = 0 J.
Explanation:
Given data:
Weight, [tex]W = 490 \ \rm N[/tex]
Height, [tex]h = 2 \ m[/tex]
The work done by a force can be expressed as,
[tex]W = F.d\textrm{cos} \theta[/tex]
Here,
W = work done
F = magnitude of applied force
d = displacement
[tex]\theta[/tex] = angle between the applied force and the displacement
Since the weight is still, therefore the magnitude of the displacement is zero.
Hence, the work done by the weight would be zero.
