Question

Using the ideas of electric field and force, explain what would happen to an electron if released from rest at r

Answer 1

Given that,

Distance = r

Electric field :

Electric field is equal to the multiplication of electric constant and charge divided by square of distance.

In mathematically form,

`E=(kq)/(r^2)`

`E=(1)/(4\pi\epsilon_(0))(q)/(r^2)`

Electric force :

Electric force is equal to the multiplication of electric constant and both charges divided by square of distance.

In mathematically form,

`E=(kqQ)/(r^2)`

`E=(1)/(4\pi\epsilon_(0))(qQ)/(r^2)`

We know that,

The relation between electric field and electric force is

`E=(F)/(q)`

According to question,

If electron is released from rest then electron move towards the source point due to attractive force.

Hence, The electron move towards the source point due to attractive force.
