Find the electric field cverywhere due to a uniform spherical charge distribution. the charge density is p(p0) and the radius of the sphere is r. a very small negative point charge,-e, and massm is placed on the surface of this charge distribution. determine the motion of this smal negative point charge assuming that it is free to move through the charged sphere without affecting the uniform charge distribution.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

If a star is moving toward earth, it is
