Gravity and Weight Conversion

Homework Statement

In Rendezvous with Rama, they are on rung 700, so about 213 m down into the ship. The gravity is very small. It says that they weigh 10 kg in that gravity. So what gravity are they in?

Homework Equations

I know I use w=ma, but how do I get the 10 kg into N? I guessed that an average male weighs 72.5 kg

The Attempt at a Solution

I tried doing 10=72.5a
a=.13

But I know that weight needs to be in N, but I'm confusing myself as to how to do that in an unknown gravity.

When it says they weigh 10kg, it means that the force of gravity on them is the same as for a 10kg mass in Earth's surface gravity, i.e. 10g N.

So you're saying I'd do:
10kg * 10 (gravity on Earth)=72.5a ??

Yes.
