Question

79.
Three different objects of masses m, m,
and
mg
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 :-​

Answer 1

Answer:

1 : 1 : 1

Explanation:

Velocity of body doesn't depend on the mass of body.

It only depends on the height of free fall.

Velocity with which the object reaches the ground v=

2gh

For all three masses, height is same and hence velocity at ground level will be same.
