40x10=400 J 

Work = Force x distance

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 :

\(W=F\times d\)

\(W=40\ N\times 10\ m\)

W = 400 Joules

So, the work done to move the block is 400 Joules. Hence, the correct option is (B) "400 J".
