When two charged, massive objects are placed a distance r apart, the gravitational force between them has magnitude F. When the distance between the objects is increased to 2r, the magnitude of the gravitational force between them becomes F/4. Did the electrostatic force between the objects also decrease to one fourth its initial magnitude as a result of the change in position, and why?

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
