<<hey,,, ur ans is SOUTH...
,B'COZ...
When an electron moving in the downward direction enters a magnetic field which is directed towards east ..When we apply FLEMMING LEFT HAND RULE here,,, in case of electron,,,, the direction of deflection will be south,, ==>Mean while if that's the case of positive charge,, then the direction of deflection of that charge,,, will be in the north,,i.e, opposite....

Hi, the above answer is wrong.
The right answer is NORTH.
Movement of electron is equivalent to movement of negative charge. Movement of positive charge is opposite to the movement of positive charge. So, Now, we have electron going downwards, i.e. positive charge going upwards.
Using Newton's third law of motion or Fleming's left hand rule, whatever you call it, we get the direction of force is NORTHWARDS.
Because middle finger points up, index finger towards the east and hence thumb forwards.
