A charged particle with a mass of 10.0 g and a charge of 50pC moves through a uniform magnetic field near the surface of the earth. The velocity is constant at 155m/s, directed perp endicularly to the surface of the earth at that point. Calculate the strength of the magnetic field at this location if the field is perpendicular the parti Cle's vel ocity.
B = (10×10-3 × 9.8)/(50×10-12 × 155 ×1)
B = 1.26×107 T
