If I could get some clarification on these three questions, that
would be great.
e. 3.05 Object (1) is a sphere (radius= R=0.80 m) with a charge den- sity of p, 960 μcoul/m². ♡ Object (2) is a cylinder having a circular cross section (radius= R=0.80 m) and a charge density of P₂. Object (1) Object (2) At a radial distance (r) from the center of object (1), the electric field magnitude is E, and at a radial distance (₂) from the axis of object (2), the electric field magni- tude is E₂. (note: In both cases, we want to be outside of the objects (i.e. r>R)) If at r = -1.6 m we find that E₁-E, then what is the value of p₂? (in ucoul/m³) a. 640 b. 480 320 8. d. 240 c. 160 0 axis

A point charge (q+400 µcoul) travels in the (+ x) direc- tion from point "a" (located at x-1 m) to point "b" (located at x-2 m); we are told that there is an electric field along the "x" axis given by E-72000x' i (N/coul). How much work is done on the point charge by the electric field for point "a" to point "b"? (in Joules) a +324 b. +216 c. + 162 d. +432 Ⓒ-108 a 12. In a region of space where the gravitational field is negligible, a small charged particle (mass-120 ukg; charge - + 480 coul) travels along the x axis. (m, g) At point "a", the potential is + 175,000 volts and the particle's speed is 3000 m/see; at point "b", the potential is + 525,000 volts; what is the speed of the particle at point "b"?
