i hope the question is understood,(adsbygoogle = window.adsbygoogle || []).push({});

the question is to prove that two masses hung from 2 strings, from the same point, at the same height from the ground, but on different length cords, can move with the same frequency, despite different lenghts

what i think needs to be done, is prove that the frequency has nothing to do with the radius of the motion but with the velocity

using equation for radial/centrepheutal force

Fr=mar=sinB*t=m(ῳ^2)R

t being tension

R-radius--->tanB*h(height)

sinB*t=m(ῳ^2)*tanB*h

cosB*t=m(ῳ^2)*h

ῳ=sqrt[mh/cosB*t]

now im not sure what to do, i have proven nothing since B is directly affectd by the lenghth of the cord, am i correct?
