I'm also having difficulty with part b of this question. I tried using a symmetry approach to try and deduce the value of |A| but in my working the |A|^2 term ends up being canceled which is of no use to me. again any pointers would be much appreciated.

ahh yes that makes it a lot clearer, thanks for the help!

1. Homework Statement I've been attempting this one for a while now and so far it has been to no avail. The question itself is in the attached document. I am given an expression that defines the wavefunction moving in 1-D over an interval and the time component is fixed with t=0. 2...

oh wait i forgot to square both sides of the equation! thanks for your help!

ok so i got angular velocity= g/Lcos(theta) but the answers tell me that it should be the sqrt of that. im a bit lost as to where i have made my mistake :S

ok so i got to tan(theta)=(v^2)/rg where r= Lsin(theta) i was thinking solve for v and then use Angular velocity=v(r) is this heading in the right direction?

the vertical components sum to zero. does the horizontal component of the tension= the centripetal force?

thanks for the welcome, so there would be a tension force through the cord, a gravitational force acting straight down and a centripetal force. am i missing anything?

This is the Diagram for the problem

1. Homework Statement A solid sphere of mass m rotates uniformly in a horizontal circle suspended from a fixed point on a cord of length L and negligible mass. The cord makes an angle theta from the vertical. What is the angular velocity? 2. Homework Equations Torque= (Rotational...
