A force F = 2x + 3 acts on a body, displacing it from x = 0 to x = 2. What is the work done?
Q1. A force F = 2x + 3 acts on a body, displacing it from x = 0 to x = 2. What is the work done?
Answer: 10 J
Explanation: Work done = ∫F dx from 0 to 2 = ∫(2x + 3) dx = [x² + 3x] from 0 to 2 = 10 J, using the formula for work done by a variable force.
