MCQ
Three different objects of masses $m_1, m_2$ and $m_3$ are allowed to fall from rest and from the same point ' $O$ ' along three different frictionless paths. The speeds of the three objects, on reaching the ground, will be in the ratio of
  • A
    $m_1: m_2: m_3$
  • B
    $m_1: 2 m_2: 3 m_3$
  • ✓
    $1: 1: 1$
  • D
    $\frac{1}{m_1}: \frac{1}{m_2}: \frac{1}{m_3}$
✓

Answer

Correct option: C.
$1: 1: 1$
(c) Speed of the object at reaching the ground $v=\sqrt{2 g h}$ If heights are equal then velocity will also be equal.
