Laws Of Motion Question 58
Question: A block of mass 2 kg rests on a rough inclined plane making an angle of 30° with the horizontal. The coefficient of static friction between the block and the plane is 0.7. The frictional force on the block is[IIT 1980; J & K CET 2004]
Options:
A) 9.8 N
B)
C)
D)
Show Answer
Answer:
Correct Answer: A
Solution:
Limiting friction
But when the block is lying on the inclined plane then component of weight down the plane
It means the body is stationary, so static friction will work on it
