Please answer all parts SHOWING ALL STEPS CLEARLY EXPLAINING THE CONCEPTS and make sure all are 100% correct solutions and do NOT use calculus (integration, Cross product, etc.) to solve any of them. Thank you!
Three parallel long straight wires arranged at the corners of an equilateral triangle carry identical currents I in the directions shown. In approximately which direction is the net force on the lower left wire? (1) downward to the left (2) left (3) upward (4) downward The gure shows a mass spectrometer in which charged particles of different masses enter a region through a slit and move perpendicular to a uniform magnetic eld per meating the region (the gray dots represent the magnetic eld pointing out of the page). The particles are measured by a detector when they strike the bottom of the region. Assume 120 and 14C singly charged ions are accelerated through the same potential difference before entering the spectrometer. If the 12C ions strike the detector 3.5 m from the slit, at one point will the 140 ions hit it? (1) 3.78 m (2) 4.08 m (3) 3.00 m (4) 3.24 m A long straight Wire and a rectangular conducting loop lie in the same plane as shown. If . the current in the long Wire is increasing, What is the direction of the net force exerted on (1) down (2) up (3) out of the page (4) into the page (5) zero . In the gure, a conducting metal bar of mass 0.75 kg, sliding along frictionless con ducting rails, is connected to a battery of emf 12 V and resistor R = 2.0 Q to form a circuit. The rails are 30 cm apart and the entire arrangement is embedded in a uniform magnetic eld 0.25 T directed into the page, as shown. When the metal bar R is momentarily at rest, what is its acceleration? (1) 0.60 m/s2 (2) 0.90 m/s2 (3) 0.45 m/s2 (4) 2.0 m/s2 (5) 2.4 m/s2Step by Step Solution
