PHYS 112 – General Physics II Spring 2010 1 Name: _______ HOMEWORK #1 – Due Friday, Jan 22 Section: _______ Consider a uniformly charged ring in the xy -plane, centered at the origin as in the figure. The ring has radius a and a positive charge q distributed evenly along its circumference. a) [1] Represent the electric field dE created by a charge element dq of the ring in the point P(0,0, z ) arbitrarily located on the z -axis. Represent the vector component of the field along the z -axis. Denote it dE z . b) [3] Notice that, by symmetry, only this z -component will contribute to the net field produced by all elementary portions of the ring. Write out a symbolical expression for the z component dE z in terms of k , dq , a and z . c) [3] To calculate the net field, integrate dE z over all circular charge. d) [1] Consider q = 16 μC, a = 0.10 m and z = h = a /100. Calculate numerically the magnitude of electric field in points P , O and , and represent the respective vector electric field in each point on the adjacent figure. z
