In the figure shown C is a fixed wedge. A block B is kept on the inclined surface of the wedge C. Another block A is inserted in a slot in the block B as shown in figure. A light inextensible string passes over a light pulley which is fixed to the block B through a light rod. One end of the string is fixed and other end of the string is fixed to A.S is a fixed support on the wedge. All the surfaces are smooth. Masses of A and B are same. Find the magnitude of acceleration of A
a) more than 6 kg
b) less than 6 kg
c) equal to 6 kg
d) none
The coefficient of friction between the surface and the block is ¼ . Then friction force acting on block is [ g = 10 m/s2] ?

a) is an inertial frame because Newton's laws of motion are applicable in this frame
b) is an inertial frame by definition
c) cannot be an inertial frame because earth is revolving around sun
d) None
Please explain
