The two main reasons that your results might not match up each time are uncontrolled conditions and experimental error.
An Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
I hope this helped you with your problem.
Answer:
a = kL/m
Explanation:
Here we can use Hooke's Law to find out the force applied on the system. Hooke's Law states that when a spring is stretched by some force, the force applied is directly proportional to the displacement of spring. The formula is given as:
F = kL
Now, the Newton's Second Law of motion states that whenever an unbalanced force is applied to a body it produces an acceleration in the body, in its own direction. So, the force is given by the formula:
F = ma
Comparing both the forces, we get:
kL = ma
<u>a = kL/m</u>
