So what i did was set up the cartesian axes $e_1-e_2-e_3$ and also the cylindrical $e_r-e_\phi$

The issue is how to calculate the cross products in the coriolis term without involving $\phi$

The issue is how to calculate the cross products in the coriolis term without involving $\phi$

As I read it, you are only asked about values in the given position.

So $\phi=\frac{\pi}{2}$ for the given position .

but the answer for accn is not matching

Just reviewd my calculations

I am unsure which part you are answering. The way a) is phrased, you are not required to calculate anything, merely provide arguments for saying whether they are the same (and that does not look hard).
Also, what is the status of your answer in post #4? Is this matching a book answer, mismatching a book answer, or there is no book answer?
