[NOTE: the numbers in this problem are unrealistic, but are more simple to work with than a more realistic situation would be.]
When two masses, Mass A and Mass B, are 1.0 m apart, they exert a gravitational force of 1 N on each other. If Mass B is replaced by Mass C which is 200 times greater than Mass B, what will be the gravitational force between Mass A and Mass C?
Remember the equation Fgrav = (mass 1 ) (mass 2)
distance2
(For this problem Mass A = 1 kg, Mass B = 1 kg, Mass C = 200 kg)

Hi
You have given us all the data, and the formula just needs to have the gravitational constant included F=GMm/d².
What would you like help with?
G=6.67300 × 10-11 m3 kg-1 s-2

from the formula given the force of gravity varies directly with the mass therefore if the mass increases by a factor of 200 so does the force of gravity. force between the new masses is 200 N

YOu know F =G M1*M2/r^2 and you know
FAB = 1 N = 1kg* 1kg/1^2m^2
Now if mass B is replaced with mascc and Mc=200*MB then
FAC = 1kg*200kg/(1m)^2 = 200*(1kg*1kg)/(1m)^2 =200 * 1 Nt =200 Nts
