Answer:
Approximately (assuming that this spring is ideal.)
Explanation:
The displacement of a spring is the new length of the spring relative to the original length.
For example:
- When the
-spring in this question is stretched to
, the displacement is
.
- Likewise, if this spring is stretched to
, the displacement would be
.
If this spring is ideal, the force on the spring would be proportional to the displacement of the spring. In other words, if a force of displaces this spring by
, while a force of
displaces this spring by
, then:
.
In this question, it is given that a force of would stretch this spring by
. Thus, the force
required to stretch this spring by
would satisfy:
.
Rearrange and solve for :
.
Answer:
The third particle should be at 0.0743 m from the origin on the negative x-axis.
Explanation:
Let's assume that the third charge is on the negative x-axis. So we have:
We know that the electric field is:
Where:
- k is the Coulomb constant
- q is the charge
- r is the distance from the charge to the point
So, we have:
Let's solve it for r(3).
Therefore, the third particle should be at 0.0743 m from the origin on the negative x-axis.
