ایک جسم معمولی جھکاؤ کے بعد غیر مستحکم توازن میں ہے اگر اس کا مرکز ثقل ______ ہے؟
A. Passes over the point of contact
B. Is positioned at its bottom
C. Remains above the point of contact
D. Remains on one side of the point of contact
Explanation
When a body is in unstable equilibrium, a slight tilt will cause its center of gravity (CG) to remain above the point of contact, making it prone to toppling over or falling.
This means that the CG is not directly over the point of support, but is still above it, creating a moment that tends to rotate the body further.
Key Points:
A body is in stable equilibrium after slight tilt if its center of gravity remains above the point of contact.
A body is in neutral equilibrium when its center of gravity remains at same height.
