Question : An electron is separated from a proton by a distance of 0.53 Å. Calculate the electric field at the location of the electron.
Doubt by Mohini
Solution : Simply use the formula of Electric field due to a point charge.
Here
r = 0.53 Å
r = 0.53×10-10 m
Q = e = 1.6×10-19 C
Here
r = 0.53 Å
r = 0.53×10-10 m
Q = e = 1.6×10-19 C
E = kQ/r²
= (9×109×1.6×10-19)/(0.53×10-10)²
= (14.4×10-10)/(0.2809×10-20)
= 51.26×1010
= 5.1 ×1011 N/C
