then, as it boils it remains at constant temp ( boiling point)
Answer:

Explanation:
We know that charge on electron

r= 2 nm
We know that force between two charge given

Now by putting the value


We know that mass of electron
The mass of electron

F= m a
a= Acceleration of electron
a= F/m


initial velocity given that zero ,u=0
