EXAMPLE 15.3 A Charge Triangle GOAL Apply Coulomb's law in two PROBLEM Consider three point charges at the corners of a triangle, as shown in the COS 36.9 figure, where q1 6.00 x 10-9 c, q2-2.00 x 109 C, and q3- 5.00 x 10-9 C. (a) Find the components of the force F23 exerted by q2 on g3. (b) Find the components of the force F13 exerted by q1 on q3. (c) Find The foroe the resultant force...
A small object with mass 3.70 kg moves counterclockwise with constant speed 6.10 m/s in a circle of radius 4.80 m centered at the origin. It starts at the point with position vector (4.80i 0 ) m. Then it undergoes an angular displacement of 9.00 rad. (a) What it its position vector? 1 + i) m (b) In what quadrant is the particle located and what angle does its position vector make with the positive x-axis? Selectat A° (c) What...
