Physics - September 2006

The objective of this question is to generate insights of how this problem could be solved using collective mankind´s knowledge.
The greatest cientist of our history didn´t solve this question yet, but now the Internet provide us a platform where colaborative knowledge share between schoolars and common people can give us a better chance to actieve this goal.

A positively charged meteorite Zapyu (no such thing, but this is a thought experiment) is falling towards Earth. After it has reached a certain speed (say, v), God decides to show who's boss --- He switches off Zapyu's gravitational field (as God only can). Whap ! Zapyu's gravitational mass also goes to zero. Since Earth now exerts no pull on Zapyu, it continues to fall, but with uniform speed v. God smiles smugly at all who watch. .
Wait, though ! Along comes the Devil, who decides to show some muscle, just to keep his vote-bank intact. Whing ! He switches on a strong upward electric field to slow down/stop Zapyu's fall.

Now speak, O wise ones. Will the Devil succeed or won't he ? If he does, it means Zapyu still has inertial mass (since the external force retards its motion) although no gravitational mass, and the equivalence principle goes for a six. If he doesn't, Zapyu's i-mass has also vanished, the e-principle holds and both God and Einstein sigh in relief.
Well ?

They ignore all the evidence saying 9/11 was an inside job and are totally brainwashed? They refuse to even look at it. And even if they do look at it, they say its not true b/c they saw an article debunking 9/11 myths/

If i wrote an article debunking the earth is round article, will people believe that too.

I am beginign to think these people are brainwashed beyond recovery.
