The gravitational force on a body of mass `1.5 ` kg situated at a point is 45 M . The gravitational field intensity at that point is .

Options

A. Potential energy will increase
B. Kinetic energy will decrease
C. Total energy will increase
D. All of these

Answer

To find the gravitational field intensity at the given point, we can use the formula for gravitational field intensity (E), which is defined as the force (F) experienced by a unit mass (m) at that point. The formula is:

\[ E = \frac{F}{m} \]

Where:
- \( E \) is the gravitational field intensity,
- \( F \) is the gravitational force,
- \( m \) is the mass of the body.

### Step-by-Step Solution:

1. **Identify the given values:**
- The gravitational force \( F = 45 \, \text{N} \) (Newtons)
- The mass \( m = 1.5 \, \text{kg} \)

2. **Substitute the values into the formula:**
\[ E = \frac{F}{m} = \frac{45 \, \text{N}}{1.5 \, \text{kg}} \]

3. **Perform the division:**
\[ E = \frac{45}{1.5} = 30 \, \text{N/kg} \]

4. **State the final answer:**
The gravitational field intensity at that point is \( 30 \, \text{N/kg} \).
