Answer:
The magnetic field in the region a < r < b is
Explanation:
If we have the a < r < b. The formula of current is:
Where:
A = area enclosed by the loop.
Itotal = total current in loop.
If we have the Ampere`s law:
Force is determined by multiplying mass and gravity (F= mg). To determine the answer, the mass of the elephant (5600 kg) is multiplied with the gravity (9.8 m/s²). The answer is 5800 N. This is the upward gravitational force that the elephant exerts on the earth.
