Q5.13Multiple correct
In Fig. 5.3, a body A of mass m slides on plane inclined at angle θ1 to the horizontal and µ1 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 θ2 to the horizontal. Which of the following statements are true?
This question refers to a figure in the original PDF.
- (a)A will never move up the plane.
- (b)A will just start moving up the plane when sin θ2 − sin θ1 µ= . cos θ1
- (c)For A to move up the plane, θ2 must always be greater Fig. 5.3 than θ1 .
- (d)B will always slide down with constant speed.
