Q1. A particle moves 5 m under a constant force of 12 N. What is the work done on the particle?

💡 Difficulty: easy | ✅ Correct: A

Q2. A force varies with position according to \(F(x)=3x^{2}\) N, where \(x\) is in meters. How much work is done moving the object from \(x=0\) m to \(x=2\) m?

💡 Difficulty: medium | ✅ Correct: C

Q3. A particle experiences a force \(F(x)=\frac{10}{x^{2}}\) N along the x‑axis. Compute the work done moving the particle from \(x=1\) m to \(x=5\) m.

💡 Difficulty: hard | ✅ Correct: C
