A 11.2 µC particle with a mass of 2.70×10-5 kg moves perpendicular to a 0.890 T magnetic field in a circular path of radius 27.7 m. How fast is the particle moving? Πνα ΑΣφ ? v = m/s Submit Request Answer Part B How long will it take the particle to complete one orbit?

B E Figure 4 In Figure 4 above a negatively charged particle of mass m and charge q=-7.5 x 106 C performs a circular motion horizontally in a clockwise direction. This motion is performed in a region with uniform magnetic field. Both magnetic fields and electric fields point downwards and have the strengths of B=0.45 T and E=150 NC respectively. Draw a free body diagram to show all forces acting on the charged particle. Calculate the period of revolution. Suppose that the electric field is removed, compare both situations.

Two blocks, M=B.00 kg and m=2.00 kg are being pulled across a rough floor(u k=0.14) by a force of FO= 68N directed 52 degrees above the horizontal, as shown. The top block m cannot slide on the bottom block so the system can be treated as a single 10.0 kg block which we will call MT Fo, M-2.0 ks 520 M-8.0kg

(+1) 12 d V = d A charged particle with a mass of 2.84×10-22 kg and a charge of ±2.87x10-17 C enters a magnetic field oriented into the page with a magnitude of 0.12 T. The particle experiences a Lorentz force with a magnitude of 5.14×10-14 N while it is inside the magnetic field. Depending on the sign of the charge, the particle will take one of two circular paths shown on the figure. What velocity did the particle have when it entered the field? m S As soon as the particle enters the magnetic field, it experiences a Lorentz force toward the top of the page. Does the particle carry a positive or a negative charge? Will the Lorentz force cause the particle to speed up, slow down, or maintain the same speed? How far away from where the charge enters the field will it exit the field? Find the distance marked "d" on the figure. There are two distances marked "d" because you were asked to decide whether the charge was positive or negative. Only one of the distances applies to your problem.…

A sample containing 12c, 16O, and an unknown isotope is analyzed in a mass spectrometer. As in the figure, the ions move around a semicircle before striking a photographic plate. The 12c* and 16ot ions are separated by 4.520 cm on the plate, and the unknown isotope strikes the plate 4.900 cm from the 12c* ions. What is the mass of the unknown element?
