Answer:
The distance of the object to the center of the earth increases.
Explanation:
The acceleration due to gravity on Earth is given by:
where
G is the gravitational constant
M is the Earth's mass
r is the distance of the object from the Earth's centre
We notice that:
- g does not depend on the mass of the object
- g is inversely proportional to r
This means that if the distance of the object from the Earth's centre increases, g decreases. So, the correct option is
The distance of the object to the center of the earth increases.
Answer:
The final kinetic energy is
Explanation:
From the question we are told that
The electric field is
The charge on the object is
The mass of the object is
The distance moved by the object is
The workdone on the object by the fields is mathematically represented as
Now this workdone is equivalent to the final kinetic energy so
substituting values
