Question 255 of 280

Consider a situation in which a ring, a solid cylinder and a solid sphere roll down on the same inclined plane without slipping. Assume that they start rolling from rest and having identical diameter. The correct statement for this situation is

Show answer and solution

Answer: (A) The sphere has the greatest and the ring has the least velocity of the centre of mass at the bottom of the inclined plane.

a=gsinθ(1+ImR2)a=\dfrac{gsin\theta }{\left(1+\dfrac{I}{m{R}^{2}}\right)}
Iring>Isolidcylinder>Isolidsphere{I}_{ring}\gt {I}_{solidcylinder}\gt {I}_{solidsphere}
⇒aring<asolidcylinder<asolidsphere\Rightarrow {a}_{ring}\lt {a}_{solidcylinder}\lt {a}_{solidsphere}
⇒vring<vsolidcylinder<vsolidsphere\Rightarrow {v}_{ring}\lt {v}_{solidcylinder}\lt {v}_{solidsphere}
