Answer

Explanation:

Step1: Recall work - formula

The formula for work is $W = F\times d$, where $W$ is work, $F$ is force, and $d$ is displacement in the direction of the force.

Step2: Identify values

Here, $F = 420\ N$ and $d=10\ m$.

Step3: Calculate work

$W = 420\times10=4200\ J$

Answer:

D. 4200 J
