Question

At what distance (in m) is the electrostatic force between two electrons equal to the weight of one?

Answer 1

Step-by-step explanation:

Given

Electrostatic force between two electrons is equal to weight of one electron

i.e.

`(kq_1q_2)/(r^2)=m_e\cdot g`

where
`q_1,q_2` are the charge of particles

`m_e=`mass of electron

r=distance between them

`(9* 10^(9)* 1.6* 10^(-19)* 1.6* 10^(-19))/(r^2)=9.11* 10^(-31)* 9.8`

`r=5.08\ m`
