Two beams of electrons, beam 1 and beam 2, are moving along straight lines perpendicular to the page. We take the page to be the xy-plane. Beam 1 is moving into the page and intersects the page at point (−2, cm, 0 cm). Beam 2 is moving out of the page and intersects the page at point (2, cm, 0 cm). The streams of electrons are otherwise identical, each carrying current of magnitude 2 A. A negatively-charged particle having charge three times that of an electron is at point (x,y) = (0cm,2cm) and has velocity (vx , vy ) = (5 × 103 m/s, −5 × 103 m/s). What is the magnitude and direction of the net magnetic force on the negatively-charged particle due to the pair of electron beams?

1). A car is moving along a straight line defined to be the positive x direction. Its velocity is measured and found to be a function of time given by Vx(t)=(alpha)t^2 , where alpha is a known constant. The car was at the point x = A at the time t = 2sec. Find the car's position as a function of time. How fast would the car be going just before it hits a wall located at x = L?...

There are two steel I beams in a construction cite. The I beam A has 3" long stringer in the middle of the beam in the center of shear web and the second beam (beam B) has multiple edge cracking (0.1" deep) due to improper rolling process in the same middle area as beam A in both top and bottom flanges. As an engineer discuss which of the discontinuities will be more likely to be considered as a defect? Why?
