Mass of an electron = 9.110 x 10⁻³¹ kg.
Mass of a proton = 1.6727 x 10⁻²⁷ kg
∴ mass of a proton/mass of an electron = 1.6727 x 10⁻²⁷ kg/9.110 x 10⁻³¹ kg.
~1836
∴ mass of a proton = 1836 x mass of an electron.
∴ mass of an electron is insignificant to the mass of an atom.
∴mass of an atom = mass of protons + mass of neutrons
Hey there! :D
Yes, indeed! Magnetic is a form of energy. It pushes or pulls to forces together. A lot of this energy is through waves, and opposite and like poles.
I hope this helps!

Answer:
(a) 8 V, (b) 144000 V, (c) 2 x 10^(-8) C
Explanation:
(a) charge, q = 5 μC , Work, W = 40 x 10-^(-6) J
The electric potential is given by
W = q V
![40\times10^{-6}=5 \times10^{-6}\times V\\\\V = 8 V](https://tex.z-dn.net/?f=40%5Ctimes10%5E%7B-6%7D%3D5%20%5Ctimes10%5E%7B-6%7D%5Ctimes%20V%5C%5C%5C%5CV%20%3D%208%20V)
(b)
charge, q = 8 x 10^(-6) C, distance, r = 50 cm = 0.5 m
Let the potential is V.
![V =\frac{k q}{r}\\\\V =\frac{9\times 10^{9}\times 8\times 10^{-6}}{0.5}\\\\V =144000 V](https://tex.z-dn.net/?f=V%20%3D%5Cfrac%7Bk%20q%7D%7Br%7D%5C%5C%5C%5CV%20%3D%5Cfrac%7B9%5Ctimes%2010%5E%7B9%7D%5Ctimes%208%5Ctimes%2010%5E%7B-6%7D%7D%7B0.5%7D%5C%5C%5C%5CV%20%3D144000%20V)
(c)
Work, W = 8 x 10^(-5) J, Potential difference, V = 4000 V
Let the charge is q.
W= q V
![8\times10^{-5}= q\times 4000\\\\q =2\times 10^{-8} C](https://tex.z-dn.net/?f=8%5Ctimes10%5E%7B-5%7D%3D%20q%5Ctimes%204000%5C%5C%5C%5Cq%20%3D2%5Ctimes%2010%5E%7B-8%7D%20C)
Well this is question is easy. I mean i’m the one to say the least, The answer is.. SIKE L bozo imagine not knowing the answer
