So I asked around irl, looks like the answer sheet is wrong. The oscillation frequency remains unchanged by gravity.

When I said frequency I was actually referring to the angular velocity \omega=2pi*f. They are practically equivalent. OK, how do I get information about the frequency/angular velocity from here?

1. A mass M is attached to a fixed spring of constant K and oscillating with an amplitude A, the spring is hung from the ceiling in a gravitational field with constant free-fall acceleration g. 2. What is the oscillation frequency? Is it affected by gravity? Mx''=-Kx-mg => ?? 3. I figured it...

Hello, The city added a new electric transformation station near my house and has recently closed down a kindergarten adjacent to it due to 'radiation safety' reasons. My house is two doors down and my mother is concerned that radiation from the station might be hazardous to her health. She...
