The Attempt at a Solution
If the two blocks were to move together when the external force of magnitude mg is applied , the acceleration would be mg/3m = g/3 . This acceleration would have to be provided by friction . Value of friction should be mg/3 . But maximum value of friction is mg/4 .
This means there will be slipping .Upper block will move but its displacement will be less than the lower block .
First three options are ruled out . I think option 4) is right.
Is that correct ?
