Three different balls of masses m1, m2 and m3 are allowed to roll from rest along three different frictionless paths OP, OQ and OR respectively from point O whose vertical height above the ground is h. The respective speeds v1, v2 and v3 at P, Q and R will be such that |

Answer» (a) V1 = ve = veExplaination: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 = 2ghFor all THREE masses, height is same and hence velocity at ground level will be same. ⟹ v1 : v2 : V3 = 1 : 1 : 1⟹ v1 = ve = ve {OPTION (a)} |
