हिन्दीA bob suspended by a string executes vertical circular motion. If the string becomes slack exactly at the highest point \( C \) and is simultaneously cut at that very instant, what is the subsequent trajectory of the bob?
Correct answer · Option 1
It executes a parabolic projectile motion with a horizontal initial velocity
Explanation
At point C, the velocity is non-zero and purely horizontal (\( v_c = \sqrt{gL} \)). Under gravity alone without string tension, the bob acts as a horizontally projected particle, describing a parabolic projectile path.
