Official Correct Choice:
Option A: Along the tangent
Concept:

Velocity is a vector pointing in the exact direction an object is heading at any given frozen split-second in time.

Solution:

  • If the centripetal force suddenly vanished (e.g., a string snaps), inertia dictates the object will fly off in a straight line.
  • This straight line only touches the curve at exactly one mathematical point.
  • A line touching a circle at exactly one point is called a tangent.
  • Thus, instantaneous velocity always points along the tangent.


Why other options are incorrect:

  • Option B is physically meaningless terminology in this context.
  • Option C and Option D describe radial motion (falling in or flying directly outward from the center), completely ignoring the forward motion.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
