A cylinder has a volume of 2.3 cm^3 and a charge density of 2.4 ?C/cm^3, and is enclosed in a spherical surface with a radius of 19 cm as shown in the figure.
1. What is the total charge on the cylinder?
2. What is the total electric flux during the surface of the sphere?
A tuning fork generates sound waves from a frequency of 246 Hz. The waves travel in opposite directions along a hallway, are reflected by end walls, and return. The hallway is 47.0m long and the tuning fork is located 14.0 m from one end.
A spider hangs from a strand of silk whose radius is5.8x10-6 m. The density of the silk is 1100kg/m3. When the spider moves, waves travel along thestrand of silk at a speed of 310 m/s. Determine the mass of the spider.
You are in the neighborhood of a star (radius of 700,000 kilometers) which has emitted so many protons ("solar wind") during its life, that it now possesses a huge net negative charge of 6 x 10^6 C, What power must the engines of the probe use in o..
A test charge of +2*10^-7 C is located 5cm to the right of a charge +1*10^-6 C and 10 cm to the left of a charge -1*10^-6 C. The three charges lie on a straight line
The charges are fixed to the corners of a 0.44-m square, one to a corner, in such a way that the net force on any charge is directed toward the center of the square.
