Aconductor is formed into a loop that encloses an area of 1.0 m2. the loop is orientedat a 30.0° angle with the xy-plane. a varying magnetic field is oriented parallel to thez-axis. if the maximum emf induced in the loop is 25.0 v, what is the maximum rate atwhich the magnetic field strength is changing

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
