Question

The upper half of an inclined plane of inclination ϴ is
perfectly smooth while lower half is rough. A block
starting from rest at the top of the plane will again come to
rest at the bottom, if the coefficient of friction between the
block and lower half of the plane is given by
(a) μ =2/tan ϴ (b) μ = 2 tan ϴ
(c) μ = tan ϴ (d) μ =1/tan ϴ

Answer 1

Answer:

sorry I didn't know that

Answer 2

Answer:

p

Explanation:

The upper half of an inclined plane of inclination ϴ is

perfectly smooth while lower half is rough. A block

starting from rest at the top of the plane will again come to

rest at the bottom, if the coefficient of friction between the

block and lower half of the plane is given by

(a) μ =2/tan ϴ (b) μ = 2 tan ϴ

(c) μ = tan ϴ (d) μ =1/tan ϴjzkzkzkddkjddjjdjdudjjjfjhfhdjdjdjdjdjddjjfjfj
