The motion would be best described as B) an up-and-down motion on the surface of the earth
Answer:
hi everybody it's Satoshi you know that
Answer:
Speed
Explanation:
The distance traveled by an object in a unit of time is speed
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:
![E_{1}+E_{3}-E_{2}=0](https://tex.z-dn.net/?f=E_%7B1%7D%2BE_%7B3%7D-E_%7B2%7D%3D0)
We know that the electric field is:
![E=k\frac{q}{r^{2}}](https://tex.z-dn.net/?f=E%3Dk%5Cfrac%7Bq%7D%7Br%5E%7B2%7D%7D)
Where:
- k is the Coulomb constant
- q is the charge
- r is the distance from the charge to the point
So, we have:
![k\frac{q_{1}}{r_{1}^{2}}+k\frac{q_{3}}{r_{3}^{2}}-k\frac{q_{2}}{r_{2}^{2}}=0](https://tex.z-dn.net/?f=k%5Cfrac%7Bq_%7B1%7D%7D%7Br_%7B1%7D%5E%7B2%7D%7D%2Bk%5Cfrac%7Bq_%7B3%7D%7D%7Br_%7B3%7D%5E%7B2%7D%7D-k%5Cfrac%7Bq_%7B2%7D%7D%7Br_%7B2%7D%5E%7B2%7D%7D%3D0)
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.
I hope it helps you!
A.
The tension is 0 because there is no net force.
B.
The tension is once again 0 because the acceleration is 0 which means there is no net force.
C.
F = ma
F = 50 kg x 5 m/s²
F = 250 N
