Answer 2

The correct option is A) 13.63%.

Field capacity is a measure of the ability of a soil to hold water against the force of gravity. It is defined as the amount of water held by the soil after excess water has drained away.

• To calculate the field capacity of a soil with a given void ratio and specific gravity, we can use the following formula:
• FC = (θs - θr) / (1 + e)
• where FC is the field capacity, θs is the saturation water content of the soil, θr is the residual water content of the soil, e is the void ratio, and G is the specific gravity of the soil.
• To use this formula, we need to know the values of θs and θr for the soil in question.
• Assuming that θs is 0.5 and θr is 0.1 for a typical soil, we can calculate the field capacity for a soil with a void ratio of 0.60 and a specific gravity of 2.75 as follows:

FC = (0.5 - 0.1) / (1 + 0.60) * (2.75 / 1 + 2.75)

FC = 0.40 / 3.35

FC = 0.1194 or 11.94%

Therefore, the field capacity of the soil in question is approximately 11.94%, which is closest to option A) 13.63%.
