Question

A particle is subjected to a force $F_x$ that varies with position as shown in figure. Find the work done by the force on the body as it moves from $x=10.0xm$ to $x=5.0xm$.

• A. $-15J$
• B. $15J$
• C. $3J$
• D. $27J$

Answer 1

The correct option is A $-15J$

$From$ $x=10m$ to $x=5m$

$S=-ve$

$F=+ve$

$\therefore W_1=-Area=-5\times 3$

$=-15J$
