Please I am begging you may I have clear working so I may understand what I doing and I am able to explain it and do others like it. Thanking you in advance.

(25 points) Two fixed points lie in the x-y plane. Relative to the origin in Cartesian coordinates, one at the location 131 : (38.2 E 63.9 f) cm and another at :3 : (17.33 42.7)?) cm . A mass m is placed at 1"} and a constant force is applied to it 13 : (13.E+ 41,?) N . Find the work on the mass by the given force in going from point one to point two. Use vector algebra to solve this problem. 3. (25 points) A \"very large cylinder with positive charge Q , radius R , and length L \" is centered on the origin of a Cartesian coordinate system. The cylinder has a uniform charge density. Find the electric field vector a distance r from the z axis, inside the charge distribution: r
