Three different objects of masses `m_(1) , m_(2)` and `m_(2)` are allowed to fall from rest and from the same point `O` along three different frictionless paths. The speeds of three objects on reaching the ground will be:

`m_1 : m_2 : m_3`.

`m_1 : 2m_2 : 3m_3`.

`1//m_1:1//m_2:1//m_3`.

`1 : 1: 1`
