A charged particle of mass 100 gm and charge +1.5 C is fixed at a position 2 m from the ground. Two charged particles of the same mass are in equilibrium 50 cm below and 60 cm above the 1st particle respectively. What is the nature and quantity of their charge?
2.61×10⁻¹¹ C and 1.72×10⁻¹¹ C
1.81×10⁻¹¹ C and -2.61×10⁻¹¹ C
-1.81×10⁻¹¹ C and 2.61×10⁻¹¹ C
1.72×10⁻¹¹ C and 2.61×10⁻¹¹ C

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
