Assertion: There are two boxes of masses 5 kg and 4 kg are in contact with the smooth inclined plane of 30 degrees and then released afterward; their acceleration is
Reason: Acceleration of the mass is
Assertion is true
Reason is true
Assertion and Reason both are true, And Reason is the correct explanation for Assertion
Assertion and Reason both are false
As the inclined plane is smooth so the acceleration of both the masses will be same
