A +4Q positively-charged metal sphere (Sphere A) and an electrically-neutral metal sphere(Sphere B) are sitting on insulated stands on a table. The two spheres are brought into contact with each other, and then the contact is broken. Using conservation of charge, which statement describes the movement of charges between the two spheres? A. Positive charge will move from Sphere A onto Sphere B, resulting in a +4Q positive charge on each sphere.
B. Negative charge will move from Sphere B onto Sphere A, resulting in both spheres becoming neutral.
C. Positive charge will move from Sphere A onto Sphere B, resulting in a +2Q positive charge on each sphere.
D. Negative charge will move from Sphere B onto Sphere A, resulting in a +2Q positive charge on each sphere

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
