Question

If the distance between two masses is increased by a factor 3, then by what factor would the mass of one of them have to be altered to maintain the same gravitational force? Would there be an increase or decrease in the mass?

Answer 1

Answer:

me reversal test is a test to determine whether a given method will work both ways in time,forward and backward, where Po1is the index for time ‘1’ on time ‘0’ as base and P10is theindex for time ‘0’ on time ‘1’ as base, i.e. Po1x P10= 1. If the product is not unity, there issaid to be a time bias in the method.Factor reversal test:If fefines that the product of price index and the quantity index should be equal to thecorresponding value index. It is given by P01x Q01= V019

Answer 2

There’s an inverse squared relationship between gravitational force and the distance between the two objects, due to the equation

$Fg= \frac{Gm1m2}{r2}$

Hence, if the distance is increased by a factor of 3, we get a factor of 1/9 . Therefore, the product of the two masses needs to increase by a factor of 9, which we can do by increasing the mass of each object by a factor of 9.
