1. Gravity from 2 point masses. Assume two equal point masses, each - [kg], are located at the points (0, -q) and (0, q). Suppose a test particle of mass m is located at a point (p, 0) along the x- axis and p > 0. (a) Explain why the total gravitational force from these two sources pull the test particle in the horizontal direction, toward the point (0, 0) . (b) Show that the total force applied to the test particle (from both source masses) equals F = GMm.p ( 12 + 9? ) 2 [Hint: Find the magnitude of the gravity caused by each mass. Pick up only the horizontal component. Force applied in this direction AL Take the sum of both horizontal components. ] part of force applied in this (horizontal ) direction . = F Cos
