Vedclass · Answer

(D) Cathode rays consist of a stream of negatively charged particles (electrons).When a negatively charged particle enters an electric field,it experiences a force in the direction opposite to the electric field.The electric field is directed from north to south.Therefore,the force on the negatively charged cathode rays will be directed from south to north.Thus,the deflection of the cathode rays is towards the north.

Cathode rays travelling from east to west enter into a region of an electric field directed towards north to south in the plane of the paper. The deflection of cathode rays is towards:
