- Homework Statement
- Hi, I am stuck at this question:

The gravitational field strength at the surface of Mars is one third that at the surface of

the Earth. A mass-spring system with a frequency of 3.0 Hz at the surface of the Earth

would have a frequency at the surface of Mars of

A 5.2 Hz

B 3.0 Hz

C 1.7 Hz

D 1.0 Hz

The answer in the mark scheme was B, I do not know why.

- Relevant Equations
- f = 1/(2pi x sqrt l/g)

I attempted using f = 1/(2pi x sqrt l/g)

For Earth I found the value of length to be 0.0276m.

Then I substituted the value in the equation, putting (1/3)g instead of g, to find the value of f in Mars. My answer is C. I am confused.

Please help me.
