Worked practice questions

As per your syllabus, work done by a force perpendicular to the displacement (e.g. centripetal force in UCM) is which?

  1. Maximum
  2. Equal to F d
  3. Half F d
  4. Zero
Show answer and solution

Correct answer: D. Zero

Your syllabus: cos 90° = 0 ⇒ W = 0. Centripetal force does no work in uniform circular motion.

As per your syllabus, the work done by a VARIABLE force F(x) over displacement from x_i to x_f is which?

  1. ∫ F(x) dx from x_i to x_f
  2. Area only of triangle
  3. F(x_f) × x_f − F(x_i) × x_i
  4. F(x_f) − F(x_i)
Show answer and solution

Correct answer: A. ∫ F(x) dx from x_i to x_f

Your syllabus: W = ∫ F(x) dx. Area under the F vs x curve.

As per your syllabus, eqn 5.9, a conservative force F(x) is related to its potential V(x) by which relation?

  1. F(x) = ∫ V dx
  2. F(x) = + dV/dx
  3. F(x) = V(x)
  4. F(x) = − dV/dx
Show answer and solution

Correct answer: D. F(x) = − dV/dx

syllabus eqn 5.9 (1D): F(x) = − dV/dx. Negative gradient of PE gives the conservative force.
