PhysicsNEET 2020Torque, angular momentum and their conservation

System of Particles and Rotational Motion

Find the torque about the origin when a force of 3j^3\hat{j} N acts on a particle whose position vector is 2k^2\hat{k} m.

  1. A.6i^6\hat{i} N·m
  2. B.6j^6\hat{j} N·m
  3. C.−6i^-6\hat{i} N·m✓
  4. D.6k^6\hat{k} N·m

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
