Two charges q1 and q2 have a total charge of 10 mu or micro cc. when they are separated by 4.1 m, the force exerted by one charge on the other has a magnitude of 8 mn. find q1 and q2 if both are positive so that they repel each other, and q1 is the smaller of the two. (for the universal constant k use the value 8.99 times 109 n m2/c2.)

Which atomic model was proposed as a result of j. j. thomson’s work?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
