Question

We can rise from a chair without bending a little forward.

(a) True

(b) False

I had been asked this question in an interview for job.

Enquiry is from Relation between Torque and Momentum topic in section System of Particles and Rotational Motion of Engineering Physics I

Answer 1

Right choice is (b) False

Easy explanation: Our weight exerts a torque about our feet. This makes it difficult for us to rise from the chair. When we bend forward, the centre of gravity of our body comes above our feet. The torque due to our weight becomes zero and we can easily rise from the chair.
