Question

A solid sphere is rolling down on inclined on plane from rest and a rectangular block of same mass is also slipping down simultaneously from rest on a similar smooth inclined plane.

• A. both of them will reach the bottom simultaneously
• B. the sphere will reach the bottom first
• C. the rectangular block will reach the bottom first.
• D. depends on density of material

Answer 1

The correct option is A both of them will reach the bottom simultaneously

As both the bodies are moving on smooth inclined plane, there will be no friction acting on the bodies thus both the bodies have some accelaration $g\sin \theta$ ths both of them will reach the bottom together .
