Question

Which tower is more likely to fall?

Answer 1

If there is no difference in angles but one has more width - this one is more likely to fall.

In physics, we use term "center of mass" (geometrical point).
The displacement of the center of mass from vertical line is higher => higher magnitude of net force => higher chance to fall.

I would say A :)

Answer 2

The tower that is likely to fall is C because both towers are more likely to fall or remain stable.

The concept at play here is center of gravity.

The center of gravity (CG) position is the average location of an object's weight. The center of gravity of an item is its balancing point, often known as the place where all of its mass seems to be located.

The following formula is used to calculate the position of the center of gravity based on the moment measurement: M = W x d: Where M is the applied moment, W is the object's weight, and d is the distance from the pivot point to the object's center of gravity.

Since both towers are the same in height and width, we can estimate that both towers are likely to fall or remain stable.
