Question

# A block of mass is resting on a rough inclined plane of inclination 30° as shown in fignre. The coefficient of friction between the block and the plane is =0.5. What minimam force shald be applied perpendicular to the plane of block does not slip on the plane ?

- acm
- 6.24 N
- 2.68 N
- 4.3 N

## The correct answer is: 2.68 N

Assertion If then

Reason If is a homogeneous function in of degree ' ' then

For such questions, we should know the formulas related to homogeneous equation. Before solving the equation, we have to see if the given function is a homegenous function. A homegenous function has same degree for all its terms.
