Answer: The correct answer is option(B).
Explanation:
Force applied on the block = 40 N
Displacement of the block = 10 m
Work done is defined as product of force applied on an object into displacement of an object.
Work done = \(Force\times Displacement\)
Work done to move the block:\(40 N\times 10 m= 40 N m=40 Joules\)
40 Joules of work was applied to move the block . Hence, the correct answer is option (B).
