Correct option is B
The correct answer is: (B) 20°
The surcharge angle (angle of repose) refers to the maximum angle at which a pile of granular material remains stable without sliding.
For paddy grains, this angle is typically around 20°, depending on moisture content, shape, and surface texture.
Information Booster:
The angle of repose is an important factor in designing storage bins, silos, and handling systems for grains.
Paddy grains have a moderate repose angle due to their lightweight husk and rough texture, which provide some resistance to sliding.
This property helps in determining the slope of grain piles in storage and transport systems.
