Q. What must the charge (sign and magnitude) of a particle of mass 1.45 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 670 N/C?

Use 9.81 m/s^2 for the magnitude of the acceleration due to gravity.

Q. The rms speed of the molecules in 1.7 g of hydrogen gas is 1800 m/s. What is the total translational kinetic energy of the gas molecules? What is the thermal energy of the gas? 500 J of work are done to compress the gas while, in the same process, 1800 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules?
