Explanation:
The electric field at a distance r from the charged particle is given by :

k is electrostatic constant
if r = 2 m, electric field is given by :

If r = 1 m, electric field is given by :

Dividing equation (1) and (2) we get :

So, at a point 1 m from the particle, the electric field is 4 times of the electric field at a point 2 m.

you have to provide mass to get acceleration
as Newton's 2nd law, force=mass×accln
now,here force toward D is 100N,if it hav mass m
then accln will be 100/m
You can make everyday count by accomplishing all the tasks you have for that day. Also you can try and find the positive throughout the day. Another thing you could do is eat a healthy meal. You can do a workout and that will make you feel better about your self. The last thing you can do is always have a good mindset about that day.
Definitely not the last 2. My bet is on the first option. If it is wrong don't hit me please...
