Question

In the following figure all surfaces are smooth. The system is released from rest, then

• A. Acceleration of wedge > g$sin\theta .$
• B. Acceleration of $m=g\sqrt{1+2co{s}^2\theta .}$
• C. Acceleration of m is g.
• D. Acceleration of wedge is g $sin\theta .$

Answer 1

Answer: (C), (D)

The correct options are
C

Acceleration of m is g.

D

Acceleration of wedge is g $sin\theta .$

As both block having same acceleration along he inclined plane which is $gsin\theta .$ Normal force between them is zero.
