(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There is a spinning disc. Object A sits R distance from center and object B sits R/2 distance away. V_{B}=piR/T and V_{A}=2piR/T

2. Relevant equations

Find the magnitude of the acceleration of object B. Assume that the cylinder makes one complete turn in a period of time .

3. The attempt at a solution

The answer is a=(2pi^{2}R)/T^{2}.

From using centripital acceleration=v^{2}/R , i got

a_{c}=pi^{2}R/T^{2}

There is a coefficient of 2 that I am missing in my answer from the correct solution, but I have double checked. Am I using the wrong formula here? where did the 2 come from in the answer?
