The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Spiraling In A proton follows a spiral path through a gas in a magnetic field of 1.11 x 10"T, perpendicular to the plane of the spiral. In two successive loops, P and Q, the radii are 9.6 mm and 8.2 mm. Calculate the change in the kinetic energy AKE of the proton as it travels from P to Q. 5 OC 0. AKE = abc sin(x Ox10 Submit Reset Reset All .First find the velocity of the proton at each radius. Recall that kinetic energy is 12mv2. .Did you check the sign of AKE -- it should be positive if KE increases, negative if it decreases
