How do we prove that tetrahedral arrangement is the arrangement which allows 4 points to be maximum apart from each other about a fixed centre, assuming that the points are all symmetrical about the centre.
(I am asking in context of the structures of the molecules like CH4, since there the...
I solved it using the work-energy theorem, by finding the energy of the system after displacing by a small amount, and the work done by the force applied at point P, somewhat similar to what someone posted there. Finding the energy is pretty long, but yes the results are simple expressions in...
This is a problem posted by a member on Brilliant.org (https://brilliant.org/problems/acceleration-of-hinges/). I found one way to solve the problem, but it is really long, and i am looking for some different solutions. The problem is-
Four similar rods of uniform density are connected with...
"Wouldn't the force give rise to a vertical component of velocity on the object"- It would, but without changing the magnitude of the velocity vector, and thus only changes the direction of velocity.
To prove this, take P to be the power of the force delivered when the object has velocity V...
