Answer:
10N/m
Explanation:
Using F=kx
F=mg
k=mg/x
k=0.1*10/0.1 (kg*m/s^2)/m
10N/m
As proton is heavier then electron, and electrostatic force is directly proportional to mass, so it would be greater and direction would be changed 'cause of different charges.
In short, Your Answer would be Option 4

Explanation:
A projectile is an object upon which the only force is gravity. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity. Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity.
