*17-84. The armature (slender rod) AB has a mass of0.2 kg and can pivot about the pin at A. Movement iscontrolled by the electromagnet E, which exerts a horizontalattractive force on the armature at Bof Fg = (0.2(10-³)) N,where I in meters is the gap between the armature and themagnet at any instant. If the armature lies in the horizontalplane, and is originally at rest, determine the speed of thecontact at B the instant / = 0.01 m. Originally / = 0.02 m.150 mmE«'A
