Question

Mass m1 moves of a slope making an angle ∅ with the horizontal and is attached to mass m2 by a string passing over a frictionless pulley. The coefficient of friction between m1 and the sloping surface is μ. Which of the following statements are true ?


1) If m1 > m2 sin∅ , the body will move up the plane
2) If m2 >m1 (sin ∅ + µcos ∅), the body will move up the plane

3) If m2 < m1 (sin∅ + µcos∅), the body will move up the plane

4) If m2 < m1 (sin ∅ – μcos∅), the body will move down the plane
​

Answer 1

Answer:

Correct option is

B

If m

2

>m

1

(sinθ+μ cosθ), the body will move up the plane.

D

If m

2

<m

1

(sinθ+μ cosθ), the body will move down the plane.

Key concept: When a mass mx is placed on a rough inclined plane: Another mass m2 hung from the string connected by ftictionaless pulley, the tension IT) produced in string will try to start the motion of mass w,.

At limiting condition,
