# A block of mass \( 4.0 \) \( \text{kg} \) rests on an inclined plane.The coefficient of static friction between the block and the plane \( \mu_s \) is \( 0.4 \).Which of the following gives the angle of inclination at which the block will start to slide?

A block of mass \( 4.0 \) \( \text{kg} \) rests on an inclined plane. The coefficient of static friction between the block and the plane \( \mu_s \) is \( 0.4 \). Which of the following gives the angle of inclination at which the block will start to slide?

- **A.** \[ \sin^{-1}(0.4) \]
- **B.** \[ \tan^{-1}(0.4) \]
- **C.** \[ \cos^{-1}(0.4) \]
- **D.** \[ \tan^{-1}(0.6) \]
