Question

A duck flying due east passes over Atlanta, where the magnetic field of the Earth is 5.2 Times 10-5 T directed north. The duck has a positive charge of 4.0 Times 10-8 C. If the magnetic force acting on the duck is 2.00 Times 10-11 N upward, what is the magnitude of the duck's velocity? Answer in units of m/s. A thin 2.21 m long copper rod in a uniform magnetic field has a mass of 40.1 g. When the rod carries a current of 0.203 A, it floats in the magnetic field. The acceleration of gravity is 9.81 m/s2 . What is the field strength of the magnetic field? Answer in units of T.

Explanation / Answer

B = 5.2*10-5 T (north), q = 4.0*10-8 C F = 2.00*10-11 N (up) find v use F = qvB v = F/(qB) = 9.62 m/s (east) L = 2.21 m, m = 40.1 g, I = 0.203 A, g = 9.81 m/s2, findB mg = IBL B = mg/(IL) = 0.876 T
