Question

Calculate the work done by the force $\overrightarrow{F}$ when the block moves from $x=3.0m$ to $x=4.0m$

• A. $4J$
• B. $0J$
• C. $-1J$
• D. $3J$

Answer 1

The correct option is B $0J$

The work done by the force is $W={\int }_3^{4}Fdx$
From the graph F is zero in between $x=3$ to $x=4$, So $W=0$
