Compare the Gravitational force to electrostatic force between two electrons ???

Answers

Answered by kushalankur09p5h135

gravitional force for electron is much much smaller that electrostatic force which is Fg/Fe = 10 to the power -43

kushalankur09p5h135: The magnitudes of the gravitational and electrostatic force are given by,

Fg=Gm1m2r2

Fe=kq1q2r2

So, the ratio is,

FgFe=Gm2eke2

Where the 1/r2 have cancelled.

Now, we use the values:

G=6.67×10−11 N-m2kg−2
me=9.1×10−31 kg
k=9×109 N-m2 C−2
e=1.6×10−19 C

FgFe=(6.67×10−11)(9.1×10−31)2(9×109)(1.67×10−19)2 = 2.4×10−43

kushalankur09p5h135: sorry in last line Fg/Fe

Dashiell: it's ok..

Dashiell: tq

Charge on an electron q=−1.6×10 −19 C

Mass of an electron ,m=9.1×10 −31 kg

gravitational constant, g=6.67×10 −11

Let the distance between two electrons =r
