A- plane mirror because its surface is plane
Answer:
Mass of the object or earth
W=F*s
W=9000*0
W=0
W:Work
F:Force
s:Distance
I think the answer is c but I’m not sure
Answer:
The force exerted on the
is ![F = 2.25*10^{3} \ N](https://tex.z-dn.net/?f=F%20%3D%20%202.25%2A10%5E%7B3%7D%20%5C%20N)
Explanation:
From the question we are told that
The area is ![A = 2.34*10^{-3} \ m^2](https://tex.z-dn.net/?f=A%20%3D%20%202.34%2A10%5E%7B-3%7D%20%5C%20m%5E2)
The magnitude of charge placed on them is ![q = 7.07 * 10^{-7} C](https://tex.z-dn.net/?f=q%20%3D%20%207.07%20%2A%2010%5E%7B-7%7D%20C)
The charge placed between the plate is ![q_1 = 6.62 *10^{-5} C](https://tex.z-dn.net/?f=q_1%20%3D%206.62%20%2A10%5E%7B-5%7D%20C)
The electric field generated around the plate is mathematically represented as
![E = \frac{q}{A \epsilon_o}](https://tex.z-dn.net/?f=E%20%3D%20%20%5Cfrac%7Bq%7D%7BA%20%5Cepsilon_o%7D)
Substituting values
![E = \frac{7.07*10^{-7}}{2.34*10^{-3} * 8.85 *10^{-12}}](https://tex.z-dn.net/?f=E%20%3D%20%20%5Cfrac%7B7.07%2A10%5E%7B-7%7D%7D%7B2.34%2A10%5E%7B-3%7D%20%2A%208.85%20%2A10%5E%7B-12%7D%7D)
![E = 34*10^{6} \ V/m](https://tex.z-dn.net/?f=E%20%3D%2034%2A10%5E%7B6%7D%20%5C%20V%2Fm)
The force exerted the charge
is mathematically represented as
![F = q_1 * E](https://tex.z-dn.net/?f=F%20%3D%20%20q_1%20%2A%20E)
Substituting values
![F = 6.62 *10^{-5} * 34*10^{6}](https://tex.z-dn.net/?f=F%20%3D%20%206.62%20%2A10%5E%7B-5%7D%20%2A%2034%2A10%5E%7B6%7D)
![F = 2.25*10^{3} \ N](https://tex.z-dn.net/?f=F%20%3D%20%202.25%2A10%5E%7B3%7D%20%5C%20N)
