Question

calculate the gravitational force between the two object ( b) both the is double (c) distance is double​

Answer 1

Answer:

F=  

R  

2

 

GMm

​  

 

(i)

If one mass say, m is doubled, then force is

F  

′

=  

R  

2

 

2GMm

​  

=2F the force gets doubled.

(ii)

If the distance is doubled and tripled-

F  

′

=  

(2R)  

2

 

2GMm

​  

=  

4

F

​  

   

and,

F  

′

=  

(3R)  

2

 

2GMm

​  

=  

9

F

​  

 

(iii)

If both masses are doubled, then force is

F  

′

=  

R  

2

 

4GMm

​  

=4F the force gets quadrupled.

Answer 2

Answer:

C,The Distance is Double
