Oscillation in a hole through the Earth (hole is offset)

[Carbon123]

1. The problem statement, all variables and given/known
There is an Earth but the hole is not in the middle but the side.find the period of oscillation

Homework Equations

Simple harmonic equation.Newton gravitational force

The Attempt at a Solution

I got GMx/R^3+acc=0 so period of osciilations is the same as when tunnel is through the center is it correct ?(that the period is the same as in the center of the earth)

 

[Bandersnatch]

so period of osciilations is the same as when tunnel is through the center is it correct ?

Yes.
