Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected? (b) If while travelling 0.200 m, with...

Tipler6 28.P.035. A current integrator measures the current as a function of time and integrates (adds) the current to find the total charge passing through it. (Because I = dq/dt, the integrator calculates the integral of the current or Q = ∫ I dt.) A circular coil that has 300 turns and a radius equal to 4.50 cm is connected to such an instrument. The total resistance of the circuit is 20.0 Ω The plane of the coil is originally...
