Two spherical balls each of mass 1kg are place 1 cm apart. Find the gravitational force of attraction between them.

Text Solution

Verified by Experts

Mass of each ball, m=1 kg:
Separation, `r= 1cm =10^(-2)` m
Gravitation force of attraction,
`F=(Gmm)/(r^2)=(6.67xx10^(-11)xx1xx1)/((10^(-2))^2)`
`=6.67xx10^(-11)xx10^4=6.67xx10^(-7)N`.
