Initially we have to know the direction of electric force on a point charge.
For the positive charge, the direction of force is same as the electric field lines and for negative charge is opposite to the filed lines.
And also, for the magnitude we know that force F=qE
The top left diagram below shows a 1-C positive charge placed in a uniform external electric...
The top left diagram below shows a 1-C positive charge placed in a uniform external electric field. The electric field in which the charge is placed is represented by field lines (drawn in red), and the resulting electric force on the charge is represented by the blue vector. Suppose the 1-C charge is removed, and is replaced, in turn, by each of the charges shown in the other three diagrams below. Assuming that the external electric field remains the same,...

The top left diagram below shows a 1-C positive charge placed in a uniform external electric filed. The electric field in which the charge is placed is represented by field lines (drown in red) and the resulting electric force on the charge is represented by the blue vector.
7. Draw a diagram of a proton and electron in a uniform electric field. Include electric field lines for the external electric field and velocity vectors for both charges (the length of the velocity vector should imply magnitude of velocity
