Wo small nonconducting spheres have a total charge of Q=Q1+Q2= 94.0 μC , Q1 A. What is the charge on each? Q1,Q2=

B. What would Q1 and Q2 be if they were attractive?

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
