Question

calculate the gravitational force between two masses of 10 kg and 20 kg if they are at 10 meter distance.

Answer 1

Answer:

mass = M = 20 kg

mass = m = 20 kg

distance = 10 m

g = GMm/r^2

6.67 × 10^ -11 × 20 ×20 /100

13.34 × 10^-11 N

or 13.34G N

hey mate,I haven't solved the last as because it will be too small

But hope it helps you

please mark as brainliest.

Answer 2

Answer:

1.3348×10^-10.

Explanation:

Given,

m1=10kg

m2=20kg

r=10m and G=6.674×10^-11 kg.m^3/s^2

f=G×m1×m2/r^2

=6.674×10^-11×20×10 /10×10

=6.674×10^-11×2

=13.348×10^-11

=1.3348×10^-10newton
