A plane inclined at angle θθ  has a velocity ratio of 10:1. The inclination of the plane to the horizontal is given by

A.

tanθ = 1/10

B.

cotθ = 1/10

C.

cosθ = 10/1

D.

sinθ = 1/10

Correct Answer:

sinθ = 1/10

Explanation

V.R = 10 / 1 = 10

V.R = 1sinθ\frac {1}{sinθ}

sinθ=0.1sinθ = 0.1

V.R = 10 / 1 = 10

V.R = 1sinθ\frac {1}{sinθ}

sinθ=0.1sinθ = 0.1
