There are some missing information in the question.
However, since you are talking about magnetic force, I think you refer to the Lorentz force. When a particle of charge q and velocity v is immersed in a magnetic field of intensity B, the force acting on the particle is:
where
is the angle between the magnetic field and the direction of the particle.
Therefore, if force F is doubled, then also the velocity v must be double of its initial value:

Answer:
The height of the object is 5007.4 miles.
Explanation:
Given that,
Weight of object = 200 lb
We need to calculate the value of
Using formula of gravitational force
Put the value into the formula
We need to calculate the height of the object
Using formula of gravitational force
Put the value into the formula
Hence. The height of the object is 5007.4 miles.
Answer:
See description
Explanation:
With the given information we have:
the interval is
now the mass has the given expression:
we will use the formula for a line integral and let:
therefore we have:
we solve the integral:
