हिन्दीIn the given diagram, a girl whirls a stone tied to a string in a horizontal circle at a constant speed \( v \). If the string breaks suddenly at the point shown, what will be the immediate trajectory of the stone relative to the ground, viewed from directly above?
Correct answer · Option 3
Tangentially to the circular path at that instantaneous position.
Explanation
By Newton's first law, once the string breaks, centripetal force ceases to act. The stone continues its motion along the direction of its instantaneous velocity vector, which is tangent to the circular path at that instant.
