13. Find all solutions to the equation. 13. (5 pts) 14. The force, F, needed to break a board is inversely proportional to the length, L, of the board. If it takes 24 pounds of force to break a board that is 2 feet long, how much force would be needed to break a board that is 5 feet long? Remember to include correct units with your answer. 14. (5 pts) number units
An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where p⃗ is the induced dipole moment, α is called the polarizability of the molecule, and E⃗ is the electric field at the molecule. A stronger electric field at the molecule results in a...
A bead of mass m slides smoothly from point A to point B on a semicircular horizontal wire loop of radius R. It is attracted toward its starting point A by a force F directly proportional to its distance r from A (for instance, you can imagine an elastic string connecting m to A). What it reaches B the force toward A is Fo. Numerical values: Fo = 2 N, R = 20 cm, m = 500 g. Calculate the...

Please explain how you approach this so I can emulate your problem solving strategies on like problems Suppose we had a large, positively charged plate in an upright (vertical) position and a point charge with positive charge +Q. In lecture, you saw that a large charged plate gives rise to an electric field which is constant in space: we will call this electric field Eplate. Let us suppose also that we had a s bl with positive charge +q and...
