Passage / Comprehension

Figure shows two masses $m_{1} = 10 k g$ and $m_{2}$ connected by a string passing over smooth fixed pulleys. Mass $m_{1}$ lies on a fixed rough surface having a coefficient of friction $μ = 0.8$ . The angle of incline $α = 3 7^{\circ}$ .

For $m_{2} = 12 k g$ , the system is released from rest at $t = 1 s$ . Choose the correct statement(s):

Options:(select one or more)

Answer:

A, B, C, D

Solution:

For $m_{2} = 12 k g$ , since $12 k g < 12.4 k g$ , $m_{1}$ will not move. Therefore, the speed of both $m_{1}$ and $m_{2}$ will always be zero. Hence, all options are correct.
