Explanation:
Both electron and proton have the same amount of charge but signs are opposite , electron contains negative charge and proton contain positive charge
Charge on 1 electron =
So charge on 206 electron
Charge on 1 proton =
So charge on 161 electron
So charge of the system =
.Answer:
The value of the work done is .
Explanation:
When a charged particle having charge is moving through an electric field
, the net force (
) on the charge is
and the work done () by the particle is
Given, .
Substitute the value of electric field in equation (1) and then substitute the result in equation (2).
