@bohotness no options I provided the answer

Answer 10

Ok this is pretty straight forward.. can you tell me exactly which part didn't you get?

Answer 11

oaky n

Answer 12

How Force and Acceleration are determined
@Mashy

Answer 13

ho,ld on okay

Answer 14

Ok.. so you have to resolve the forces.

It is clear that the particles experience no net acceleration in the y direction.
There fore the net force in the y direction must be zero
Or total upward force = total down ward force.

upward force is F
Downward forces are tensions which are angled theta with vertical.
So their vertical component would be Tcos(theta)

So total downward force is 2 T cos(theta)

These must be equal to keep the acceleration IN THE Y DIRECTION zero!.

cool?

Answer 15

Ok .Then how
acceleration = Tsin (theta)/m is determined

Answer 16

From the above you can calculate the tension

And what is accelerating the particles in the x direction?
the component of the tension along x
It is this force taht must be equal to ma

Answer 17

@Mashy thanks :)

Answer 18

sure :D

Answer 19

You can actually thank me by viewing my most recent science video and give me a feed back
Its about gravity and escape speed (fast versions.. 4 mins)

Looking forward for the feed back :D
