 (a) As in  Q.6 Similarly it is found that Hence, Next Question :

Two blocks and ( ) are connected with a spring of force constant and are inclined at a angel with horizontal. If the system is released from rest, which one of the following statements is/are correct? a) Maximum compression in the spring if there is no friction anywhere b) There will be no compression or elongation in the spring if there is no friction any where c) If is smooth and is rough there will be compression in the spring d) Maximum elongation in the spring is if all the surfaces are smooth
