The electrostatic force (not energy) of attraction between two oppositely charged objects is given by the equation $F = \kappa \frac{Q_1 Q_2}{d^2}$ where $\kappa = 8.99 \times 10^9 \text{ Nm}^2/\text{C}^2$, $Q_1$ and $Q_2$ are the charges of the two objects in Coulombs, and $d$ is the distance separating the two objects in meters. The charges $Q_1$ and $Q_2$ will have the magnitude $1.60 \times 10^{-19} \text{C}$. Part A What is the electrostatic force of attraction (in Newtons) between an electron and a proton that are separated by $0.9 \times 10^2 \text{ pm}$? Express your answer to two significant figures and include the appropriate units. $-2.8 \times 10^{-8} \text{ N}$ Submit Previous Answers ? Correct Part B The force of gravity acting between two objects is given by the equation $F = G \frac{m_1 m_2}{d^2}$, where $G$ is the gravitational constant, $G = 6.674 \times 10^{-11} \text{N} \cdot \text{m}^2/\text{kg}^2$. $m_1$ and $m_2$ are the masses of the two objects, and $d$ is the distance separating them. What is the gravitational force of attraction (in Newtons) between the electron and proton? Use the same distance: $0.9 \times 10^2 \text{ pm}$. Mass of an electron, $m_e = 9.109 \times 10^{-31} \text{kg}$ Mass of a proton, $m_p = 1.673 \times 10^{-27} \text{kg}$ Express your answer to two significant figures and include the appropriate units.

Problem 2: The Pascal (Pa) is a small unit of pressure. To show this: 1) convert 1.00 Pa = 1.00 N/m² to lb/in² (psi); 2) convert 50.0 MPa to N/m², then to lb/in² (psi) 3) a given pressure level is 40.0 lb/in² and how many Pascals is this? 4) convert 1.00 MPa to kips/in² (ksi) 5) If a given speed is 120 kilometers per hour, how many miles per hour is it? 6) If a given speed is 70 miles per hour, how many kilometers per hour is it?
