Solution

The correct option is A The block A moves down the plane.
Net force of $A = m g (sin 60 - sin 30) = m g (\frac{\sqrt{3}}{2} - \frac{1}{2})$
The block A moves down the plane.

Q. Two blocks each of mass

are resting on a frictionless inclined plane as shown in figure. Then which of the following statement about the blocks is correct?

A block of mass M is resting on an inclined plane as shown in the figure. The inclination of the plane to the horizontal is gradually increased. It is found that when the angle of inclination is $θ$ , the block just begins to the slide down the plane. What is the minimum force F applied parallel to the plane that would just make the block move up the plane?
