Two blocks of masses and are connected through a massless inextensible string. Block of mass is placed at the fixed rigid inclined suface while the block of mass hanging at the other end of the string, which is passing through a fixed massless frictionless pulley shown in figure. The coefficient of static friction between the block and the inclined plane is 0.8 . The system of masses and is released from rest. (take )

Options:(select one or more)

Answer:
A, B, C
Solution:

, so the system stays at rest without friction: - (A).

No friction acts, so the contact force is purely the normal reaction along the normal - (B), (C).
