Question

Find the work done for the force-displacement plot shown below.

• A. 120J
• B. 60J
• C. 240J
• D. 180J

Answer 1

The correct option is B

60J

Since work done is a scalar product of force and displacement, it can be calculated as area under the force-displacement plot.
So, work done = area of the right angled triangle = $\frac{\left(\right(30-0)\times (4-0\left)\right)}{2}$ = 60 J.
