A uniform magnetic field passes through a square loop of wire (side length 0.3 m) at an angle of 550 with respect to the plane of the loop.  The strength of the magnetic field is steadily increased from 4 T to 10 T in 2 s.  The resistance of the wire is 2 Ω.  What current is induced in the wire?

Two point charges are located on the x-axis. Charge q1 = 6 uC is located at the origin and charge q2 = -3 uC is located at x = 2 m.  Find the magnitude of the force  that a 2 uC charge would experience if it were placed at y = 1 m on the y-axis (point (0,1)). (This is the same setup as last question)
