Options

A. gravitational intensity
B. electric intensity
C. magnetic intensity
D. gravitational constant

Answer

To solve the question, "The force experienced by a unit mass at a point in the gravitational field is called its," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gravitational Field**:
- A gravitational field is a region in space where a mass experiences a force due to the presence of another mass. The strength of this field can vary depending on the mass and distance.

2. **Defining Unit Mass**:
- A unit mass is typically defined as a mass of 1 kilogram (kg). When we talk about the force experienced by a unit mass, we are referring to the gravitational force acting on this 1 kg mass.

3. **Gravitational Force**:
- The gravitational force (F) acting on a mass (m) in a gravitational field (g) can be expressed by the formula:
\[ F = m \cdot g \]
- For a unit mass (m = 1 kg), the force simplifies to:
\[ F = 1 \cdot g = g \]

4. **Gravitational Intensity**:
- The term used to describe the force experienced by a unit mass in a gravitational field is known as "gravitational intensity" or "gravitational field strength." This is denoted by the symbol \( g \).

5. **Conclusion**:
- Therefore, the answer to the question is that the force experienced by a unit mass at a point in the gravitational field is called "gravitational intensity."

### Final Answer:
The force experienced by a unit mass at a point in the gravitational field is called its **gravitational intensity**.
