Given→

Gravitational force between two masses M1 and M2 with a force F acting and r being the distance between two objects. Gravity is fully covering the universe. Gravity pulls the weight.

m1= 10kg

m2= 20kg

G= 6.673 x 10^-11Nm^2kg^-2

r = 5

F = Gm1m2/r²

F = (6.673 x 10^-11 x 10 x 20)/5²

F = 6.673 x 8 x 10^-11

F = 53.3 x 10^-11 N

Answer 2

Answer:

53.36 × 10^-11

Explanation:

G = 6.67 × 10^-11

F = G × m1 × m2 / r^2

= 6.67 × 10^ -11 × 10 × 20 / 25

Since 10 and 20 and 25 will cancel so the answer will be

= 6.67 × 10^-11 × 2 × 4

= 53.36 × 10^-11N
