When subjected to a transverse electric field, cathode rays move.
A
Down the potential gradient
B
Up the potential gradient
C
Along a hyperbolic path
D
Along a circular path
Answer

Explanation
Solution
In an electric field, a force opposite to the direction of electric field acts on negatively charged particles (i.e. from lower potential to higher potential).
