Acontainer with volume 1.77 l is initially evacuated. then it is filled with 0.226 g of n2. assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. if the root-mean-square speed of the gas molecules is 178 m/s, what is the pressure of the gas?

P=1587.18 Pa

Explanation:

Given that

V= 1.77 L =1.77 x 10⁻³ m³

m = 0.226 g

Vrms= 178 m/s

We know that ideal gas equation

P V = n R T

M=Molecular wight of the gas

P M = m R T             -----------1

P=Pressure ,V=Volume  ,n=Moles,R=Gas constant ,T=temperature

        ------2

From above two equation we can say that

P=1587.18 Pa

The pressure of the gas is 1587.18 Pa

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
