It is a great channel for a physics enthusiast. Keep making awesome videos
Thanks a lot! Much appreciated!
This is a very nice illustration. We may apply this to a electric field as well. Your fantastic vedio gave me the idea.
Suppose, there is a uniformly charged ring of radius r, having a net charge q and there is a charged bead of mass m on the axis, at a distance x from the centre, having charge - Q, which on the influence of the electric field, performs simple harmonic motion for small x
Here actually, we can say for small x, the term (r^2+x^2)^(3/2) becomes r^3
So the force is - kQqx/r^3,
ma=-kQqx/r^3
a=(k/m)/r^3. Qq. x
Acellaration is proportional to displacement. This helps to interpret.
oh no
Watching this when i have an exam on 3 hours ahhh
Good luck!
i finally got what shm meant THANK U SO MUCH
Amazing, thanks for the comment!
Can I ask, when you said that the force is acting upwards when we pull it down because it wants to return to equilibrium, we are also applying a force on it to pull it down right? Do we not think about that when we are looking at SHM?
good question, this is the initial force, SHM starts once this force is removed typically for a free oscillation. Sometimes you can have a forced oscillation in which the force is still there. Hope this helps!
can you show why a=-ω^2x? i want to know how it is derived

im watching a day before paper 1 ahhh
Good luck!
