Question

The gravitational force produced between two bodies is 10N when they are kept at a distance of
4m. How much gravitational force is produced when they are kept 2m apart? (Ans:40N)
​

Answer 1

Explanation:

Data

Force=10N

Distance= 4m

force=?

distance= 2m

Solution

= F= k×m1×m2

D^2

And ;

= f = k×m1×m2

d^2

If ;

= F×D^2= k× m1 × m2

and;

= f×d^2 = k×m1×m2

So;

= F × D^2 = f × d^2

= F×D^2 =f

d^2

= 10N×(4m)^2 = f

(2m)^2

= 10N×16m^2

4m^2

= 160Nm^2

4m^2

= 40 N. proved your answer
