This is because the earth is way heavier than Jessica hence has a greater force of gravity applied on Jessica that Jessica applies to earth. The distance between the Earth and Jessica is also very short hence the force of gravity on Jessica towards earth is greater. According to Newton's laws that states; if an unbalanced force acts on an object, it will change the object's state of motion (the object will accelerate). The earth cause Jesica to ‘accelerate’ towards the ‘core’ when she stumbles.
Answer:
The magnitude of the electric field in the second case will be of the electric field in the first case
Explanation:
The electric field at a distance < R from the center of the sphere is given by
the formula =
where R is the radius of the sphere, and, Q is the charge uniformly distributed on the sphere.
It is given that the same charge Q is distributed uniformly throughout a sphere of radius 2R and we have to find the electric field at same distance from the center.
In the second case the electric field will be given by
=
Therefore the magnitude of the electric field in the second case will be of the electric field in the first case.
