Two blocks A and B of mass 5 kg and 2 kg, respectively, connected by a spring of force constant 100 N/m are placed on an inclined plane of inclination 30° as shown in the figure. If the system is released from rest, then
- There will be no compression or elongation in the spring if all the surfaces are smooth.
- There will be elongation in the spring if A is rough and B is smooth.
- Maximum elongation in the spring is 35 cm if all surfaces are smooth.
- There will be elongation in the spring if A is smooth and B is rough.
Answer
(A) There will be no compression or elongation in the spring if all the surfaces are smooth., (D) There will be elongation in the spring if A is smooth and B is rough.
