The magnitude of the force between two point charges 1.0 m apart is 9 x 10^9N . If the distance between them is doubled, what does the force become? a. 0.65 x 10-4N
b. 2.25 x 10°N
c. 3.75 x 10-6N
d. 1.76 x 10°N

Why there is no inductive reactance in dc circuits

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively
