In a figure a body A of mass m slides on plane inclined at angle θ1 to the horizontal and μ is the coefficient 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 an angle θ2 to the horizontal. Which of the following statements are true?
