Q5.12Multiple correct
Mass m1 moves on a slope making an angle θ with the horizontal and is attached to mass m2 by a string passing over a frictionless pulley as shown in Fig. 5.2. The co-efficient of friction between m1 and the sloping surface is µ. Which of the following statements are true? m1 m2
This question refers to a figure in the original PDF.
- (a)If m 2 > m 1 sin θ , the body will move up the plane.
- (b)If m 2 > m1 ( sin θ + µ cos θ ) , the body will move up the plane.
- (c)If m 2 < m1 ( sin θ + µ cos θ ) , the body will move up the plane. Fig. 5.2
- (d)If m 2 < m 1 ( sin θ − µ cos θ ) , the body will move down the plane.
