To determine how the acceleration of the body changes when half of the net force is applied, we can use Newton's second law of motion, which states:
\[ F = m \cdot a \]
where:
- \( F \) is the net force applied,
- \( m \) is the mass of the body, and
- \( a \) is the acceleration.
In the first trial, if the net force is \( 0.7 , N \), we can express the acceleration as:
\[ a_1 = \frac{F_1}{m} = \frac{0.7 , N}{m} \]
In the second trial, if half of the net force is applied (\( 0.7 , N / 2 = 0.35 , N \)), the new acceleration will be:
\[ a_2 = \frac{F_2}{m} = \frac{0.35 , N}{m} = \frac{0.7 , N}{2m} = \frac{a_1}{2} \]
Thus, the acceleration in the second trial is half of its original value.
The correct response is:
The acceleration is half of its original value.
