Question

what will be the force of gravity between two objects of mass 1kg each with a distance of 1m between their centres​

Answer 1

$\bold{\huge\underbrace{\overbrace{\boxed{\boxed{\mathfrak{Answer:}}}}}}$

$\bold{Given\;:m_1=m_2=1\:kg,r=1m}\\\\\bold{Force\:of\:gravitation\:F=\frac{Gm_1m_2}{r^2} }\\\\\large\boxed{\mathfrak{F=\frac{6.67*10^-11*1*1}{1^2} }} = \bold{6.67*10^-11\:N.}$

What happens to the force of attraction between two objects when their masses are half? \

When distance between objects is doubled, force of attraction will become 122=14 times i.e. will become one-fourth. (3) When distance between objects is halved, force of attraction will become 1(12)2=114=4 times i.e. will become four times.
