A wedge of mass `m` is placed on a smooth fixed horizontal surface and block of mass `m` is placed on smoth inclined surface of wedfe as shown. The system is then released from rest. (`g` is acceleration due to gravity)

Select correct option(s)

Answer

A, D

Explanation

The accelration `a` of wedge is `a = (gsinthetacostheta)/(1 + sin^(2)theta) = (g)/(3)`
`:.` The compounds of accelertion of block along

and normal to incline are
Hence vertical compount of acceleration of block is
`a_(y) = asin^(2)theta + gsintheta costheta = (2g)/(3)`
