Two particles of masses `1kg` and `2kg` are placed at a distance of `50cm`. Find the initial acceleration of the first particle due to gravitational force.

Explanation

Gravitational force between two particles
`F=(Gm_(1)m_(2))/(r^(2))=(6.67xx10^(-11)xx1xx2)/((0.5)^(2))=5.3xx10^(-10)N`
The acceleration of `1Kg` particles is
`a_(1)=F/(m_(1))=(5.3xx10^(-10))/1=5.3xx10^(-10)ms^(-2)` towards the `2Kg` mass
