A positive charge of 50.0 nC is distributed uniformly throughout the volume of a nonconducting sphere of radius a. This nonconducting sphere is placed at the center of a conducting spherical shell of inner radius b and outer radius c, as shown in the figure below. The conducting shell carries a net charge of 250 nc: What are the charges on the inner and outer surfaces of the conducting shell? Insulator Conductor OA Cannot be calculated without knowing the radius a of the insulating sphere. O B. qinner = -50.0 nC, and gouter = +25.0 nc Ginner = +25.0 nC, and 9outer = -50.0 nc OD. 9inner = 0, and gouter = +25.0 nc O E. 9inner = +50.0 nc, and g, -75.0 nC

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
