A force F = 2x + 3 is applied on a body. What is the work done in displacing the body from x = 0 to x = 2?
Q1. A force F = 2x + 3 is applied on a body. What is the work done in displacing the body from x = 0 to x = 2?
Answer: 10 J
Explanation: Work done = ∫F dx from 0 to 2 = ∫(2x + 3) dx = [x² + 3x] from 0 to 2 = 2² + 3*2 = 10 J.
