Question

Ratio of magnitude of electric force in air and water between electron and proton

Answer 1

Answer:

Explanation:

Let us assume that the gravitational force is given as :

Fg=GMmr2

And Electrostatic force is given as :

Fe=kq1q1r2

where k is a constant, and k=9×109,

Moreover,q_1 = q_2 & M = m, since they are electrons.

Now taking the ratio of gravitational to electrostatic force, we get :

FgFe=Gm2kq2

Putting in the values,

FgFe=2.427×10−43
