See the figure below. A uniform electric field exists in the region between two oppositelycharged parallel plates. A particle with charge –3.90 nC is placed in the electric field. Which of the...

Now we know that direction of electric field is positive to negative charge.So direction of electric field will be from positive plate to negative plate.So direction of electric field is left to right
Since charge particle is negatively charge it will be attracted towards the positive plate.So...
