Advanced Circular MotionHardQuestion 5336

Question

In a vertical circle of radius R, the minimum speed at the bottom to complete the loop is:
  1. A
    √(gR)
  2. B
    √(2gR)
  3. C
    √(5gR)
    Correct
  4. D
    √(3gR)

Correct answer

√(5gR)

Explanation

Minimum speed at top = √(gR). Energy conservation: v_bottom² = gR + 4gR = 5gR → v_bottom = √(5gR).
