Question

Select the correct figure(s) that represents unstable equilibrium point.

• A.
• B.
• C.
• D. Both (b) & (c)

Answer 1

The correct option is D Both (b) & (c)

Under unstable equilibrium, once the ball is disturbed from its initial equilibrium point, it fails to regain the equilibrium state. So, both (b) & (c) are correct.

Hence option D is the correct answer
