Question

Statement -1:  A sphere and a cylinder slide without rolling from rest from the top of an inclined plane. They will reach the bottom with the same speed. 

Statement -2 :  Bodies of all shapes, masses and sides slide down a plane with the same acceleration. 

(A) Statement - 1 is correct (true), Statement - 2 is true and Statement- 2 is correct explanation for Statement - 1 

(B) Statement -1 is true, statement -2 is true but statement-2 is not the correct explanation four statement -1. 

(C) Statement - 1 is true, statement-2 is false 

(D) Statement-2 is false, statement -2 is true

Answer 1

Correct option: (A) Statement - 1 is correct (true), Statement - 2 is true and Statement- 2 is correct explanation for Statement - 1

Explanation:

if a body slides down an inclined plane then acceleration is a = g(sinθ – μ cosθ) i.e. a is function of g, θ and μ only. i.e independent of shapes, masses and sides.
