Explanation:
Let g' = the gravitational field strength at an altitude h
We also know that g at the earth's surface is
Since g' = (2/3)g, we can write
Simplifying the above expression by cancelling out common factors, we get
Taking the square root of both sides, this becomes
Solving for h, we get
Complete Question:
In the same configuration of the previous problem 3, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 13.5 cm. Each wire carries 7.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3.
a) Draw a diagram in a (x,y) plane of the four wires with wire 4 perpendicular to the origin. Indicate the current's directions.
b) Draw a diagram of all magnetic fields produced at the position of wire 3 by the other three currents.
c) Draw a diagram of all magnetic forces produced at the position of wire 3 by the other three currents.
