If the masses of two planets doubles and the distance between them reduces by half, the force between them would be
let
m1= mass of the planet 1st
m2= mass of the second planet
d= distance between the planets
force between two planets is
F = (G m1 m2 )/(d2 )
now the masses of the planets becomes doubled and distance is reduce to half then
"m1 " becomes "2m1 " and "m2 " becomes "2m2" and "d" becomes "d/2" then force becomes
F' = (G 2m12m2) / (d/2)2 = 4Gm1m2 / ( d2/4)
F' = 16(G m1 m2 )/(d2 ) = 16F
the force between them would be BECOMES 16 TIMES OF INITIAL FORCE

Consider a pair of planets for which the distance between them is increased by a factor of three. Show what happens to the force of attraction between these two planets.
Two bodies are exerting a gravitational force of 100N on each other. If the mass of each body doubles and the distance between them stays the same, what is the new gravitational force between them?
How would the force of gravity between two masses be affected if the separation distance between them were the following? (Assume F2 represents the new force and F1 represents the original force.) (a) double the original distance (b) one-fifth the original distance
How would the force of gravity between two masses be affected if the separation distance between them were the following? (Assume F2 represents the new force and F1 represents the original force.) (a) quadruple the original distance F2 / F1 = (b) one-third the original distance F2 / F1 =
Please solve step by step explain If the distance between two charges doubles, the electric (Coulomb) force between them... becomes one-fourth quadruples halves doubles stays the same
Two masses, m1 and m2 are separated by a distance, r. The force of attraction between the two masses is F. If the original force is 20N and both masses quadruple while the r decreases to ¼ of the original distance: A) how much would F change? B) what will be the new force?
the gravitationl force between two masses placed a certain distance away is mesured to be 50 N if the distance between them is halved then the new forces between the two obj will be 25N 100N 200N 50N
Two bodies with masses m1 and m2 are located in some distance ‘d’ between each other.they are attract each other with the gravity of force 1N.what is the gravity force between anther two bodies if their masses and the distance between each other are greater exactly twice than for the first bodies?
the force of gravity between two masses is 26 N when they are 7.5 apart. the distance between them is changed and the force increases to 71 N. how far apart are they now?
Part A Is there change in the torce of gravity between two objects when their masses are doubied and the distance behwaen them is also doubled? The force of gravity is doubled The force of gravity is tripled O The force of gravity is quadrupled There is no change. Submi Request Answer Provide Feedback
