Answer:
r = 9.92 mm
Explanation:
Given that,
Mass of oil drop, ![m=2\times 10^{-15}\ kg](https://tex.z-dn.net/?f=m%3D2%5Ctimes%2010%5E%7B-15%7D%5C%20kg)
It acquires 2 surplus electrons, q = +2e ![=3.2\times 10^{-19}\ C](https://tex.z-dn.net/?f=%3D3.2%5Ctimes%2010%5E%7B-19%7D%5C%20C)
Potential difference, V = 620 V
Thie potential difference is applied between the pair of horizontal metal plates the drop is in equilibrium.
We need to find the distance between the plates.
At equilibrium,
mg = qE
Since, E = V/r (r is distance between plates)
![mg=\dfrac{qV}{r}\\\\r=\dfrac{qV}{mg}\\\\r=\dfrac{3.2\times 10^{-19}\times 620}{2\times 10^{-15}\times 10}\\\\=0.00992\ m\\\\=9.92\ mm](https://tex.z-dn.net/?f=mg%3D%5Cdfrac%7BqV%7D%7Br%7D%5C%5C%5C%5Cr%3D%5Cdfrac%7BqV%7D%7Bmg%7D%5C%5C%5C%5Cr%3D%5Cdfrac%7B3.2%5Ctimes%2010%5E%7B-19%7D%5Ctimes%20620%7D%7B2%5Ctimes%2010%5E%7B-15%7D%5Ctimes%2010%7D%5C%5C%5C%5C%3D0.00992%5C%20m%5C%5C%5C%5C%3D9.92%5C%20mm)
So, the distance between the plates is 9.92 mm.
Answer:
Emergency Room or a Clinic
Explanation:
The Emergency Room if in a hospital. A Clinic may also see patients without insurance, but they're not on Emergency Room grounds.
Answer:
2.5 N
because Average speed is equal to distance divided by time
The electrostatic force is directly proportional to the product of the charges, by Coulomb's law.
F α Qq
If the charges are now half the initial charges:
<span>F α (1/2)Q *(1/2)q
</span>
F α (1/4)Q<span>q
The new force when the charges are each halved is (1/4) the first initial force experienced at full charge.</span>
