We're told that the mass of each particle is m.
The gravitational field is expressed as:
The magnitude of gravitational field for each particle on the y-axis is given by:
Two identical particles, each of mass m, are located on the x axis at x = + x0 and x = - x0.
A. Determine a formula for the gravitational field due to these two particles for points on the y axis; that is, write as a function of y, m, x0, and so on.
B. At what point (or points) on the y axis is the magnitude of a maximum value, and what is its value there? [Hint: Take the derivative dg/dy.]
C. What is the maximum value of the magnitude of g?
