A thin rod rotates at a constant angular speed. In case A the axis of rotation is perpendicular to the rod at its center. In cas
e B the axis is perpendicular to the rod at one end. In which case, if either, are there points on the rod that have the same tangential speeds?

Answer:
50,000 V/m
Explanation:
The electric field between two charged metal plates is uniform.
The relationship between potential difference and electric field strength for a uniform field is given by the equation
where
is the potential difference
E is the magnitude of the electric field
d is the distance between the plates
In this problem, we have:
is the potential difference between the plates
d = 15 mm = 0.015 m is the distance between the plates
Therefore, rearranging the equation we find the strength of the electric field:
