A uniform, square metal plate with side L = 6.57 cm and mass 0.211 kg is located with Its lower left corner at (x,y) = (0,0) as shown in the figure. Two squares with side length L/4 are removed from the plate.
a) What is the x-coordinate of the center of mass?
b) What is the y-coordinate of the center of mass?
If the magnitude of an electric field in air is as great as 3.00×106 N/C, the air becomes ionized and begins to conduct electricity. This phenomenon is called dielectric breakdown. A charge of 13.0 C is to be placed on a conducting sphere. What is th..
