Option D is correct : This positive charge will veer east
It is given that the particle has a positive charge.
So, the <u>direction of the force</u> on the positive charge (and also the acceleration) is in the <u>same direction</u> as the electric field.
Now the<u> electric field is uniform</u> and points in east, the<u> force</u> on it
will also be pointed towards the east.
The positive charge was initially <u>moving north</u>, which means that the velocity vector was in the direction of north and when a <u>positive charge</u> first reaches an area with an electric field and force pointing east, its velocity vector will change to be along the electric field, or east.
That’s why a<u> positive charge </u>traveling north enters a region where the electric field is uniform and points east will veer east.
