Question

A body is placed over an inclined plane of angle $\pi -\theta$. The angle between normal reaction and the weight of the body is:

• A. equal to the angle of friction
• B. more than $\theta$
• C. less than $\theta$
• D. $\theta$

Answer 1

Answer: (D)

$\theta$

From the figure,
The angle between normal reaction ($N$) and weight ($W$) is $=\pi -(\pi -\theta )=\theta$
