Question

compare the force of gravitation in both the cases​

Answer 1

Answer:

7 m < 3 m

Explanation:

force of gravitation =k q 1  . q 2 /r^2 ,here distance varies and all charges are same and k ] which is constant , so know for 7 m  ,force of gravitation less as compared to that of 3 m

Answer 2

As we know that gravitational force is inversely proportional to square of distance between two objects so,here mass of objects in both is same but distance between objects is different

hence,the gravitational force in second case is 9/49 is greater than first case.
