Assertion: When you lean behind over the hind legs of the chair, the chair falls back after a certain angle.
Reason: Centre of mass lying outside the system makes the system unstable.
Reason: Centre of mass lying outside the system makes the system unstable.
View answer and explanation
Correct option: C
If Assertion is correct but Reason is incorrect.
Option C is correct. The assertion is correct; the chair tips when the center of mass goes beyond the support. However, the reason is incorrect because the center of mass doesn't necessarily have to lie outside the system to make it unstable; it's about its position relative to the support base.
