Center of Mass/Torque

So, I have recently learned about ‘Centers of Mass’ and have discovered I was completely ignorant to the fact that the point where a force is applied will determine whether the force is a rotational force or a normal force.

Naturally, I have a few questions.

Q1: I have two objects on the ground, that are say at-least 2 cm apart, and center of mass is between the two objects. Does that mean if I applied a net force at the centre of mass the system of objects would move in that direction?

Q2: I have attached an image, in the image, we are looking at 3 objects with masses $5$$kg$, $2$$kg$ and $3$$kg$ in red dots respectively all sitting on a horizontal axis. We are defining $bar{x}$ as the location of the center of mass from the point A and the total weight of this system is $W=10g N$

Now, in the next line, finding the torque about A and defining clockwise as positive.

$$10gbar{x} = 5g(2) + 2g(3) + 3g(6) $$

Now, I don’t understand how this is so because, I thought that force applied at the centre of mass would move the object(s) in the direction in which the force was applied. So, basically there would be no torque and the weight of the system of objects would just move the system downwards, since weight acts downwards. So $10gbar{x} = 0$
