Question

study the four situations given in the following diagrams. In which case is the force of gravitation maximum?​ please help

Answer 1

Step-by-step explanation:

The gravitational force is given by :

`F=(Gm_1m_2)/(d^2)`

Force in option (1) is :

`F_1=(Gm^2)/(d^2)`

Force in option (2) is :

`F_2=(Gm* (m)/(4))/(((d)/(2))^2)\\\\F_2=(G* (m^2)/(4))/((d^2)/(4))\\\\F_2=(Gm^2)/(d^2)`

Force in option (3) is :

`F_3=(G* 2m* 2m)/((2d)^2)\\\\F_3=(4Gm^2)/(4d^2)\\\\F_3=(Gm^2)/(d^2)`

Force in option (4) :

`F_4=(G* (m)/(4)* 4m)/(d^2)\\\\F_4=(Gm^2)/(d^2)`

It is clear that in all the cases the force of gravitation is the same.
