AIPMT PRELIMS 2005 Physics Work Done by a Variable Force MCQ Question
Type: MCQ-numerical-Medium-Class 11
A force F acting on an object varies with distance x as shown here. The force is in N and x is in m. The work done by the force in moving the object from x = 0 to x = 6 m is :
A
10.5 J
B
13.5 J
C
8.5 J
D
6.5 J
Correct Answer
Option B
Detailed Explanation
The work done is the area under the force-distance graph. The area consists of a rectangle and a triangle. Calculating the total area gives 10.5 J.
