Two electrons are initially at rest separated by a distance of 2nm. At time t=0, they start to move apart due to Coulombic repul sion. How long does it take for them to separate to a distance of 20nm?
1 answer:
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
