Point A is at a lower electrical potential than point B. An electron between them on the line joining them will
A. Move towards A
B. Move towards B
C. Move at right angles to the line joining A and B
D. Remain at rest
Answer: Option B
Solution(By Examveda Team)
Since we know that electric currents move from a higher potential or a lower potential. Also, electrons move in the direction opposite to electric current. So the electron on the line joining two points A and B will move from lower to higher potential i.e, it will move towards B.This Question Belongs to General Knowledge >> Physics

It is easier to roll a stone up a sloping road than to lift it vertical upwards because
A. Work done in rolling is more than in lifting.
B. Work done in lifting the stone is equal to rolling it.
C. Work done in both is same but the rate of doing work is less in rolling.

The absorption of ink by blotting paper involves:
A. Viscosity of ink
B. Capillary action phenomenon
C. Diffusion of ink through the blotting
D. Siphon action
electron being a negatively charged moves from negative end to positive and positive plate is always at higher potential than a negative plate.therefore electron moves from lower potential(-ve) to higher potential end(+VE)
Electrons moves from lower potential to higher potential hence the ans is towards B
Right Baiju..electron flow from B to A ..
Electron flow from higher potential to lower potential . here B have higher potential.. Hence electron moves towards A
