Answer:
The work done to move the block is 400 Joules.
Explanation:
It is given that,
Force acting on the block, F = 40 N
The distance covered by the block, d = 10 m
We need to find the work done by the block. The work done by an object is given by :
[tex]W=F\times d[/tex]
[tex]W=40\ N\times 10\ m[/tex]
W = 400 Joules
So, the work done to move the block is 400 Joules. Hence, the correct option is (B) "400 J".
