A rod of length ? with uniform charge per unit length ? , where ? > 0, is placed a distance d from the origin along the x axis. A similar rod with the same charge is placed along the y axis as in the figure. Consider only a small segment of length ? x (it is of infinitesimal length) on the horizontal rod, which is placed along the x axis. The segment is at a distance x from the origin, Determine the electric field? E at the origin due to this segment. Determine the electric field ~ E rod1 at the origin due to the entire horizontal rod.Determine the electric field ~ E tot at the origin due to both rods.
A ball rolling along at speed v without slipping on a horizontal surface while it comes to a hill that rises at a constant angle above the horizontal.
what is the smallest value d can have before the string breaks?
What plate separation is required for a parallel plate.
Below are birds-eye views of six identical toy cars moving to the right at 2? Various forces act on the cars with magnitudes and directions indicated below. All forces act in the horizontal plane and are either equivalent or at 45 or 90 degrees to ca..
A shotgun fires a large number of pellets upward, with some pellets traveling very nearly vertically and others as much as 1.0o from the vertical. suppose that the initial speed of the pellets is uniformly 150ms-1 and ignore air resistance.
A laboratory ultracentrifuge is designed to produce a centripetal acceleration of 5.0 x 10^6 g at a distance of 4.00cm from the axis. What angular velocity in rev/min is necessary.
When she gets off the ride, she uploads the scale readings to a computer and creates a graph of scale reading versus time. Note that graph has a minimum value of 519 rm N and a maximum value of 666 rm N.
A bullet is fired through a board 10.0 cm thick in such a way that the bullet's line of motion is perpendicular to the face of the board. The initial speed of the bullet is 400 m/s and it emerges from the other side of the board with a speed of 30..
The gravitational force exerted on a baseball is 2.23 N down. A pitcher throws the ball horizontally with velocity 14.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 169 ms. The ball starts from rest.
