L. B A positively charged particle is tied by a massless string and allowed to move on a smooth plane, as shown in the picture. A uniform magnetic field B = 1 T is applied perpendicular to the plane pointing down. The length of the string is L = 25 cm. The mass of the particle is m = 35 kg. The charge on this particle is q = 0.65 C. The velocity of the motion is a constant v = observing from above the plane.

Figure 8 shows a coaxial cable (two nested cylinders) of length l, inner radius a and outer radius b. Note that l >> a and l >> b. The inner cylinder is charged to +Q and the outer cylinder is charged to −Q. The cable carries a current I, which flows clockwise. Use Ampere’s Law to calculate themagnetic field B⃗ at r<a, a<r<b, and r>b.
A long, cylindrical conductor of radius R carries a current I as shown in the figure below. The current density J, however, is not uniform over the cross section of the conductor but is a function of the radius according to J = 4br2, where b is a constant. a) r1 < R Note: See image for the original question and figure. I just need help with part a, not part b.
