Answer:
The velocity is
.
Explanation:
Given that,
Charge density of the plane ![\sigma=7.65\times10^{−4}\ C/m^2](https://tex.z-dn.net/?f=%5Csigma%3D7.65%5Ctimes10%5E%7B%E2%88%924%7D%5C%20C%2Fm%5E2)
Distance = 1.05 mm
We need to calculate the electric field due to plane of charge
Using formula of electric field
![E=\dfrac{\sigma}{2\epsilon}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%5Csigma%7D%7B2%5Cepsilon%7D)
Put the value into the formula
![E=\dfrac{7.65\times10^{−4}}{2\times8.85\times10^{-12}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B7.65%5Ctimes10%5E%7B%E2%88%924%7D%7D%7B2%5Ctimes8.85%5Ctimes10%5E%7B-12%7D%7D)
![E=4.322\times10^{7}\ N/C](https://tex.z-dn.net/?f=E%3D4.322%5Ctimes10%5E%7B7%7D%5C%20N%2FC)
We need to calculate potential difference
Using formula of potential difference
![V=E\times r](https://tex.z-dn.net/?f=V%3DE%5Ctimes%20r)
Put the value into the formula
![V=4.322\times10^{7}\times1.05\times10^{-3}](https://tex.z-dn.net/?f=V%3D4.322%5Ctimes10%5E%7B7%7D%5Ctimes1.05%5Ctimes10%5E%7B-3%7D)
![V=4.5381\times10^{4}\ Volt](https://tex.z-dn.net/?f=V%3D4.5381%5Ctimes10%5E%7B4%7D%5C%20Volt)
We need to calculate the work requires to be done to reach the surface of the plane
Using formula of work done
![W=qV](https://tex.z-dn.net/?f=W%3DqV)
Put the value into the formula
![W = 1.6\times10^{-19}\times4.5381\times10^{4}](https://tex.z-dn.net/?f=W%20%3D%201.6%5Ctimes10%5E%7B-19%7D%5Ctimes4.5381%5Ctimes10%5E%7B4%7D)
![W=7.26096\times10^{-15}\ J](https://tex.z-dn.net/?f=W%3D7.26096%5Ctimes10%5E%7B-15%7D%5C%20J)
We need to calculate the velocity
Using work energy theorem
![W=\dfrac{1}{2}mv^2](https://tex.z-dn.net/?f=W%3D%5Cdfrac%7B1%7D%7B2%7Dmv%5E2)
![v^2=\dfrac{2W}{m}](https://tex.z-dn.net/?f=v%5E2%3D%5Cdfrac%7B2W%7D%7Bm%7D)
![v=\sqrt{\dfrac{2\times7.26096\times10^{-15}}{1.67\times10^{-27}}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cdfrac%7B2%5Ctimes7.26096%5Ctimes10%5E%7B-15%7D%7D%7B1.67%5Ctimes10%5E%7B-27%7D%7D%7D)
![v=2.94\times10^{6}\ m/s](https://tex.z-dn.net/?f=v%3D2.94%5Ctimes10%5E%7B6%7D%5C%20m%2Fs)
Hence, The velocity is
.
Answer:
The correct answer is - fight or flight response or reaction.
Explanation:
According to Cannon, the fight or flight reaction is a strong emotion experienced by a person especially people experiences associated with a perceived threat.
This reaction takes place in form of arousal in a perceived threat or stress conditions. It helps in maintaining the body environment in panic or stressed conditions.
