Answer:
The point that would have the same electric field as P is
from the center of the sphere.
Explanation:
From the question we are told that
The radius of the sphere is 
The Electric field at point P is
The distance of point P from the center is
Since the electric is directed radially outward it mean this it would be felt both inside and outside the sphere
The Electric field inside the sphere at a distance z is mathematically represented as

where k is the coulomb's constant with a value 
q is the charge
The Electric field inside the sphere at a distance D is mathematically represented as

To obtain the point of equal electric field


We have that

Substituting values


Answer:
O B. when the angle between the force and displacement is 90°
Explanation:
<h3>work defined as

. </h3><h3>work can only be done if object moves(displacement) in the direction of force. now a quick one. if you since the varrious angles into the cosine, you would see that Cos 90 will give zero which implies that no work is done. Again, angle means it is perpendicular and so it is not in the direction of force.</h3>
Answer:
Democritus
Explanation:
Democritus was a Greek philosopher who was the first person to use the term atom . However ,John Dalton was the first to adapt Democritus’ theory into the first modern atomic
model
