Question

two shower each of mass 1000kg with center distance 1m a apart find the gravitational force with which attract each other.

f= G m1 m2 / r2

Answer 1

F = G m1 m2/ r2
F = 9.8 x 1000 x1000 /1^2
F = 9800000

Answer 2

Gravitational force is given by :-

F=Gm1m2/r^2

Given data :-

m1 =m2=1000kg

r=1m

And we know that G is gravitational constant ,its value is 6.67×10^_11Nm^2/kg^2

Now F=Gm1m2/r^2

F = 6.67×10^_11 × 1000 ×1000/1^2 (1000×1000=10^6 , and 1^2 = 1 )

F = 6.67×10^_11 × 10^6

F = 6.67 ×10^_11+6

F = 6.67×10^_5 N
