9TA: Tomoyuki Nakayama Monday, March 28, 2011 PHY 2048: Physics 1 with Calculus, Spring 2011 Review: Chapter 13.1-13.6 The purpose of this review is to refresh your memory. Physics is a cumulative subject, so make it sure you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter! ________________________________________________________________________________ A . Newton’s Law of Gravitation & Superposition Principle In the right figure, particles are located at the center and on the perimeter of a square of length L = 0.50 m. What the net gravitational force on the particle at the center if M = 2.0 kg? B. Gravitational Potential Energy The figure on the right shows two concentric spherical shells with radii R 1 = 0.20 m and R 2 = 0.40 m and masses M 1 = 3.0 kg and M 2 = 9.0 kg. A particle of mass m = 1.0 kg is brought to the center of the shells from infinity due to an external force. Find the net work done by the force.
