Consider a regular hexagon of side length, L=10cm. A charge, Q=2uc, is located at each vertex(there are 6).
a) find the electostatic potential at the center of the hexagon
b) find the electric field vector at the center
c) find the electric field at the center if there is no charge at one of the vertices.
d) is there a contradiction between your answers to (a) and (b)? if not, then explain why.
An 8-g bullet is fired into a 170 g block that is initially at rest at the edge of a table of 1m height. The bullet remains in the block, and after the impact the block lands d = 2.10 m from the bottom of the table. Determine out the initial speed..
A microscope with an eyepiece lens of focal length 1.90 cm and an objective lens of focal length 1.15 cm is used to examine a section of the brain of a sacrificed rat. The distance between the lenses of the instrument is 24.0 cm and final image is vi..
Consider an airplane flying at Mach 4 at 70,000 feet. A shock is formed due to supersonic flow. Find the total pressure at the nose using 3 approaches
Suppose you have a thin, uniform rod with a total mass of 3.00 kg and a total length of 2.00 m. By what percent- age does the moment of inertia decrease if you rotate it about a point located 20% (0.40 m) from one end, instead of at that end?
A cylinder with a piston contains 0.250 mol of oxygen at 240000 pascal and 355 kelvin. The oxygen may be treated as an ideal gas. The gas first expands isobarically to twice its its original volume. It is y then compressed isothermally back to its..
Calculate the magnetic field at the observation location. The space shuttle releases a satellite into the circular orbit 565 above the Earth. How fast must the shuttle be moving (relative to Earth) when the release occurs.
0.75 kg block of ice is sliding by you on a very slippery floor at 2.5 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.003 seconds. The block eventually slides at an angle of 22 de..
A 240g ball and a 130g ball are connected by a 32 cm-long massless, rigid rod. The structure rotates about its center of mass at 150rpm.
A string with linear density 2g/m is stretched along the positive x-axis with tension 20 N. One end of the string, at x = 0, is tied to a hook that oscillates up and down at a frequency of 100 Hz with a maximum displacement of 1.0 mm. At t = 0s, t..
An object is thrown vertically upward and has a speed of 20.0 m/s when it reaches two thirds of its maximum height above the launch point, determine The velocity of the object at maximum height
How far does the car go before it stops. An advertisement claims that a sportscar can accelerate from rest to 100 km/hr in 7.70 s.
A skier wears a jacket filled with goose down that is 15 mm thick. Another skier wears a wool sweater that is 7.00 mm thick. Both have same surface area.
