Answer to Problem 1RCQ

Solution:

Most alpha particles emerging from a gold foil are undeflected, because the alpha particle pass through the empty space in the atom. And some are repelled because more massive cores of atoms of the same kind.

Explanation of Solution

Conceptual Physics (12th Edition), Chapter 32, Problem 1RCQ

Most of the atoms have empty space inside them. The radius of an atom is about 100000 times greater than the radius of its nucleus. So, nucleus occupies a very small volume of the atom. Alpha particles are deflected only by the nucleus. This deflection is due to the electromagnetic force between the proton of the nucleus and those of the alpha particle.

Hence, most of the time the alpha particle would pass through the empty space in the atom and not be deflected.

Conclusion:

Thus, the alpha particles emerging from a gold foil are undeflected.

as a hiker in glacier national park, you need to keep the bears from getting at your food supply. You find a campground that is near an outcropping of ice. Part of the outcropping forms a feta=51.5* slopeup that leads to a verticle cliff. You decide that this is an idea place to hang your food supply out of bear reach. You put all of your food into a burlap sack, tie a rope to the sack, and then tie a bag full of rocks to the other end of the rope to act as an anchor. You currently have 18.5 kg of food left for the rest of your trip, so you put 18.5 kg of rocks in the anchor bag to balance it out. what happens when you lower the food bag over the edge and let go of the anchor bag? Determine the acceleration magnitude a of the two-bag system when you let go of the anchor bag?
