Answer:
The magnitude of the acceleration is equal to 19.6m/s² and the acceleration is directed upwards though the magnitude of the charge has doubled. This is because the electric force is directed upwards and from newton's second law of motion the charge will have acceleration in the same direction as the electric force on the charge.

Answer:
a.After second Mr Comer's speed
b.Distance travelled by Mr.Comer in seconds
Explanation:
a. Lets recall our first equation of motion
Now we know that ,
and
Plugging the values we have.
Then Mr.Comer's speed after sec
b.
Lets find the distance and recall our third equation of motion.
So distance covered.
Dividing both sides with 2a we have.
Plugging the values.
So Mr.Comer will travel a distance of .
