A spatially uniform magnetic field B changes with time and induces an electric field E in a region of three-dimensional space containing the origin. The electric field is E = k(sin theta, cos theta) N/C at the point (x, y, z), where theta = arctan(y/x), and k = 5.3.
(a) Determine the rate of change of the magnetic flux through the circle x2 + y2 = 4.0 m2 in the xy plane? Suppose that the area normal points in the positive z direction.
(b) Assuming that the flux is zero at time t = 0 second, determine the flux through the circle when t = 10 second?
(c) Find what is the magnetic field strength at t = 10 second?

Consider a bright star in our night sky. Assume its distance from Earth is 28.1 light-years (ly) and its power output is 4.00 1028 W, about 100 times that of the Sun. Find the intensity of the starlight at the Earth
There are four charges, each by a magnitude of 1.83C. Two are positive and two are negative. The charges are fixed to the corners of a 0.367-m square, one to a corner, in such a way that the net force on any charge is directed toward the center of th..
