Physics - NLM Question with Solution | TestHub

In figure, a body A of mass $m$ slides on plane inclined at angle ${\theta }_1$ to the horizontal and ${\mu }_1$ is the coefficent of friction between A and the plane. A is connected by a light string passing over a frictionless pulley to another body B, also of mass $m$, sliding on a frictionless plane inclined at angle ${\theta }_2$ to the horizontal. Which of the following statements is INCORRECT ?
