Vertical Circle — Tension at BottomHardQuestion 30619

Question

A ball (mass m) moves in a vertical circle (radius r). Tension at the bottom when moving at speed v_b is:
  1. A
    mv_b²/r
  2. B
    mv_b²/r − mg
  3. C
    mg
  4. D
    mv_b²/r + mg
    Correct

Correct answer

mv_b²/r + mg

Explanation

At the bottom: T − mg = mv_b²/r (centripetal direction is upward). T = mg + mv_b²/r.
