In position time graphs, otherwise known as distance time graphs, acceleration/decceleration occurs when the line curves, which looks like the picture I've included.
In hours 2 to 3, the object does not accelerate, but instead stays at a constant speed of 20m per hour.

Answer:
Explanation:
The electric force exerted on the electron is given by:
where
is the magnitude of the electron charge
E = 40000 V/m is the electric field
Substituting,
By comparison, the gravitational force exerted on the electron is:
where
is the mass of the electron
g = 9.8 m/s^2 is the acceleration due to gravity
Substituting,
