What will be the gravity if we dig a hole in earth?

How deep will we have to go(on average) before drilling hits only liquid
rock(lava) ?? Trebert

In many places it’ll be less than 5 km.

In Russia they’d figured 15 km would be into liquid sulphur.

In Antarctica it could take 30+ km or as little as 1 km where it’s
geothermally active as is.

Iceland is essentially a pretty damn thin crust, whereas in places
it’s fully liquid at just a few meters underground.

Try to remember that Earth is 98.5% hot fluid, not including our
oceans. It’s quite a wonder that we can even survive on this ball of
mostly liquid minerals. Good thing basalt is such a terrific
insulator.

People drill to depths of 2 - 5 kms into the ground here in Iceland
for water, I think you´ll go much deeper than that to reach magma.

As in Hawaii, in places it's flowing magma on the surface of Iceland,
so that's actually minus a few meters deep.

Otherwise, within a relatively cool and solid basalt surface location,
I suppose a 5 km hole would more than do the trick.
