The velocity of the block at bottom is √2gR. Now for the block to complete the circle the velocity required is greater than or equal to √5gR/2 but the velocity is less than this there it cannot complete the circle. To oscillate in the lower half, it's velocity should be leads than or equal to √gR, but that is again not the case, therefore the block will go in the upper half and fall down like a projectile that is will not complete the circle. So in the conclusion we can say that the maximum height attained by the block is more than R/2 but less than R.
