The Electric Field – W1D3 • No QUIZ today. First quiz next Friday • CLICKERS: MONDAY START • Last Time • Coulombs' Law • Vector Notation: <a,b,c> • Superposition • Symmetry • Today – The concept of the Electric Field • Possibly some discussion about the electric dipole • Next Major Topic: Charge and Matter • Note: There is a NEW WebAssign that will appear sometime today. Topic: E-Field
In the figure, what are the horizontal and vertical components of the resultant electrostatic force on the charge in the lower left corner of the square if q = 1.5 x 10-7 C and a = 4.0 cm? (Assume the positive directions are upward and to the right.) y 2 3 r2 r3 1 x r1 Note that r goes from the origin to the point where we are computing the force. For our example, r=0.
