Question

A single force acts on a particle P, and the direction of the force can be changed. Rank each of the orientations of the force shown below according to the magnitude of the time rate of change of the particle's angular momentum about the point O, least to greatest.

Answer 1

explain answer also please

Answer 2

1. Don't save pictures in a friggin docx-file, pls. Not all of us are using M$-Software or have LibreOffice installed and it serves absolutely no purpose.

2. This belongs to the physics-group, I'd argue.. -> http://openstudy.com/study#/groups/physics

Answer 3

modulus of angular momentum can be expressed like the function of the sin of angle that the position vector and the force form. So for the same force it will be maximum when the angle is 90º, minimum when 0º

Answer 4

yeh physics is slow sometimes...also saving the file from a pdf file over to a doc was quicker by a fraction of second...heh sorry

Answer 5

1,2,4,3 i think

Answer 6
