In this why can't we just use the o.6o as the perpendicular distance between the forces
and where is the pivot :/

 

[princess Anu]

Why can't we consider the car and balancing weight as a single object and add their masses and subsitute them in the formula F=ma where F will be the total weight of both?

 

[princess Anu]

Why isn't it C? cause minimum force will be when force is applied furthest point from the hinge right ?
