Ametal blade (length = 80 cm) spins at a constant rate of 10 radians/s about a pivot at one end. a uniform magnetic field of 2.0 mt is directed at an angle of 30° with the plane of the rotation. what is the magnitude of the potential difference between the two ends of the blade?

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

dang that balls went far

that the claims meet official rules.

don't misinterpret the claims
