10 . Clearly the electron went opposite to the direction of the field vector,from negative to the positive plate due to an attractive force,so in this process it had undergone an acceleration due to the force generated due to the electric field.
So,if the electric field strength is
So,acceleration caused is
As,the force acting is constant,so we can apply
Given,
So,solving the above,we get,
9 . The charge lies at a distance (
So,force that will be acting on a point charge at origin,due to this
So,electric field at origin will be
Similarly at point
So,similarly electric field value will be
